This restores Windows platform file handling back to open files non-exlusively by default, as was the case before October 2018. (See b902a2f2a7)
Back then, while fixing warnings for MSVC, the function used for opening files was changed from _wfopen() to _wfopen_s() as suggsted by the warning C4996. ("This function may be unsafe, consider using _wfopen_s instead.")
This new function
1. did parameter validation and thus avoided some possible security issues due to nil pointers or wrongly terminated strings
2. it also changed the default file sharing for opened files from _SH_DENYNO (which was the implicit default for the previous _wfopen()) to _SH_SECURE.
_SH_DENYNO means every opened file could be opened by other calls (like is the default on other operating systems).
_SH_SECURE means if the file is opened with READ access, others can still read the same file, but if it is opened with WRITE access, others can't open it at all, not even to read.
This led to rarely occuring bugs on Windows, i.e. due to random access by Antivirus processes, or Godot/Windows not closing a file handle fast enough while trying to open it again elsewhere (i.e. project.godot, instead showing the Project manager, or saving shaders/debugging the game).
What this PR does it change the file access to a third method, _wfsopen(). This is still secure, doing parameter validation and thus avoids the warning, but it allows us to actually SET the file sharing parameter. And we set it to _SH_DENYNO, as it was implicitely before the change. (And as it currently is on all non-Windows platforms, where file sharing restrictions don't exist by default.)
Warning C4996 should really have been pointing this out. It should've been _wfsopen() all along. Let's hope this banishes those annoying, rare errors for all eternity.
Fixes#28036.

Change incorrect `[/code]` closing tags to `[/url]` tags.
The `url` tags for the links to the Unicode code points information use `[/code]` rather than `[/url]` to close them.
This results in the links being rendered incorrectly in the IDE--the entire rest of the documentation for each method gets turned into a giant underlined link.
This issue was introduced in a2271ba3bd.

Emscripten is LLVM-based so we want to follow the same logic. But we can't just
put it as a match in `methods.using_clang()` as that would mess with the
compiler version detection logic used to restrict old GCC and Clang releases.
(cherry picked from commit 34421683eb)
It's raised for us on many comparators implemented to be able to store a struct
in `Set` or `Map` (who rely on `operator<` internally). In the cases I reviewed
we don't actually care about the ordering and we use the struct's function
pointers as that's the only distinctive data available.

This is incorrect and not fully implemented, and results in inconsistency in the UI and in the hovering variable.

From empirical testing, this seems to provide the best compression
compared to other compression algorithms when used in the
Multiplayer Bomber demo.
Other algorithms may provide better compression ratios for more
complex games, but some compression is probably better than
no compression.
Zstandard was also not very efficient in my testing, so I added
a note in the documentation.
Extremely long frames caused by suspending and resuming the machine could result in an overflow in the delta smoothing because it uses 32 bit math on delta values measured in nanoseconds.
This PR puts a cap of a second as the maximum frame delta that will be processed by the smoothing, otherwise it returns the frame delta 64 bit value unaltered. It also converts internal math to explicitly use 64 bit integers.
Added one more warning to the hideable warnings. These seem to be benign warnings and are hidden during use in rooms and portals. When used from other areas, only one warning is displayed per run, instead of for every occurrence.
Same thing that was already done in 2D, applies moving platform motion
by using a call to move_and_collide that excludes the platform itself,
instead of making it part of the body motion.
Helps with handling walls and slopes correctly when the character walks
on the moving platform.
Also made some minor adjustments to the 2D version and documentation.

When synchronizing KinematicBody motion with moving the platform using
direct body state, only the linear velocity was taken into account.
This change exposes velocity at local point in direct body state and
uses it in move_and_slide to get the proper velocity that includes
rotations.
