internal_format() and same_leader() (John Marriott)

Problem: When calling an API from Vimscript to set an option, mapping,
etc., :verbose shows that it's set from an API client.
Solution: Don't override current_sctx.sc_sid when calling an API from
Vimscript. Also fix the inverse case where API channel id is
not set when calling an API from RPC. Move channel id into
sctx_T to make saving and restoring easier.

Problem: ins_str() is inefficient by calling STRLLEN()
Solution: refactor ins_str() to take a length argument
and let all callers provide the correct length
when calling ins_str() (John Marriott)

Problem:
The way option scopes currently work is inflexible and does not allow for nested
option scopes or easily finding the value of an option at any arbitrary scope
without having to do long handwritten switch-case statements like in
`get_varp()`. `.indir` is also confusing and redundant since option indices for
each scope can be autogenerated.
Solution:
Expand option scopes in such a way that an option can support any amount of
scopes using a set of scope flags, similarly to how it's already done for option
types. Also make options contain information about its index at each scope it
supports. This allows for massively simplifying `get_varp()` and
`get_varp_scope()` in the future by just using a struct for options at each
scope. This would be done by creating a table that stores the offset of an
option's variable at a scope by using the option's index at that scope as a key.
This PR also autogenerates enums for option indices at each scope to remove the
need for `.indir` entirely, and also to allow easily iterating over options all
options that support any scope.

Use the grapheme break algorithm from utf8proc to support grapheme
clusters from recent unicode versions.
Handle variant selector VS16 turning some codepoints into double-width
emoji. This means we need to use ptr2cells rather than char2cells when
possible.
Problem:
Variables are often assigned multiple places in common patterns.
Solution:
Replace these common patterns with different patterns that reduce the
number of assignments.
Use `MAX` and `MIN`:
```c
if (x < y) {
x = y;
}
// -->
x = MAX(x, y);
```
```c
if (x > y) {
x = y;
}
// -->
x = MIN(x, y);
```
Use ternary:
```c
int a;
if (cond) {
a = b;
} els {
a = c;
}
// -->
int a = cond ? b : c;
```
Problem: More code can use ml_get_buf_len() instead of STRLEN().
Solution: Change more STRLEN() calls to ml_get_buf_len(). Also do not
set ml_line_textlen in ml_replace_len() if "has_props" is set,
because "len_arg" also includes the size of text properties in
that case. (zeertzjq)

A lot of functions in move.c only worked for curwin, alternatively
took a `wp` arg but still only work if that happens to be curwin.
Refactor those that are needed for update_topline(wp) to work
for any window.

Problem: too many STRLEN calls when getting a memline
Solution: Optimize calls to STRLEN(), add a few functions in memline.c
that return the byte length instead of relying on STRLEN()

Problem: Things that temporarily change/restore curwin/buf (e.g:
win_execute, some autocmds) may break assumptions that
curwin/buf is the cmdwin when "cmdwin_type != 0", causing
issues.
Solution: Expose the cmdwin's real win/buf and check that instead. Also
try to ensure these variables are NULL if "cmdwin_type == 0",
allowing them to be used directly in most cases without
checking cmdwin_type. (Sean Dewar)
Reset and save `cmdwin_old_curwin` in a similar fashion.
Apply suitable changes for API functions and add Lua tests.

Problem: formatting long lines is slow
(kawaii-Code)
Solution: optimize gq (internal_format) for long
lines (kawaii-Code)
Implemented two workarounds that significantly reduce
the amount of pointless calls. Ideally the algorithm
would be rewritten not to be n^2, but it's too complicated
with too many corner cases.

Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
Problem: Many places in the code use `findoption()` to access an option using its name, even if the option index is available. This is very slow because it requires looping through the options array over and over.
Solution: Use option index instead of name wherever possible. Also introduce an `OptIndex` enum which contains the index for every option as enum constants, this eliminates the need to pass static option names as strings.
Problem: The entire marktree needs to be traversed each time a sign is
removed from the sentinel line.
Solution: Remove sentinel line and instead keep track of the number of
lines that hold up the 'signcolumn' in "max_count". Adjust this
number for added/removed signs, and set it to 0 when the
maximum number of signs on a line changes. Only when
"max_count" is decremented to 0 due to sign removal do we need
to check the entire buffer.
Also replace "invalid_top" and "invalid_bot" with a map of
invalid ranges, further reducing the number of lines to be
checked.
Also improve tree traversal when counting the number of signs.
Instead of looping over the to be checked range and counting
the overlap for each row, keep track of the overlap in an
array and add this to the count.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
Problem: CI: test_termdebug fails
Solution: only test for a changed winlayout, if the window
width actually changed
Also, include an unrelated comment (which doesn't warrant its own patch
number)

long is 32 bits on windows, while it is 64 bits on other architectures.
This makes the type suboptimal for a codebase meant to be
cross-platform. Replace it with more appropriate integer types.

- Move vimoption_T to option.h
- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h

libnvim couldn't be easily used in C++ due to the use of reserved keywords.
Additionally, add explicit casts to *alloc function calls used in inline
functions, as C++ doesn't allow implicit casts from void pointers.
Problem: Code is indented more than necessary.
Solution: Use an early return where it makes sense. (Yegappan Lakshmanan,
