In x11, windows and osx crash handlers, check project settings exists
before looking up the crash handler message setting.
Avoids crashing the crash handler when handling a crash outside project
settings lifetime. Instead omitting the configurable message and
continuing with trace dump.

Maximum stack size is only 8KiB, this will try to allocate 8193 *
sizeof(void*) * 2 = 131088 bytes on the stack. This causes a crash in
some cases.

It appears that Object::script may be a valid ScriptInstance but not be
castable to Ref<Script>. There were only 5 places in the code that made
this assumption. This commit fixes that.

We used to abort if the system-specific data folder (e.g. `~/.local`
or `%APPDATA%`) is missing, but the next code chunk actually creates
it with `make_dir_recursive` if missing.
Fixes#26598.

It is not valid in C++ to store into shadow_matrix1[16] with shadow_matrix1[16 * j]
(for j > 0). Even though there's a valid space in a struct after shadow_matrix1.
Knowing that GCC performs aggressive optimizations that eventually lead
to a wrong code. Code has been changed into union where one can either
use shadow_matrix[4 * 16], or individual shadow_matrix1, shadow_matrix2, etc. GCC pragma
is not needed any longer.

Godot supports many different compilers and for production releases we
have to support 3 currently: GCC8, Clang6, and MSVC2017. These compilers
all do slightly different things with -ffast-math and it is causing
issues now. See #24841, #24540, #10758, #10070. And probably other
complaints about physics differences between release and release_debug
builds.
I've done some performance comparisons on Linux x86_64. All tests are
ran 20 times.

I have also looked at FPS numbers for tps-demo, 3d platformer, 2d
platformer, and sponza and could not find any measurable difference.
I believe that given the issues and oft-reported (physics) glitches on
release builds I believe that the couple of percent of tight-loop
floating point performance regression is well worth it.
This fixes#24540 and fixes#24841

Seemingly a typo, I did not check what exact impact it had, but
the x_ofs would likely have accumulated errors when using fonts
with varying char widths.

Also used in non-ES platforms where an extra-copy is avoided.

Fix for incorrect types used in MeshDataTool for bones and weights.
If your mesh contains these memory accesses get OOB and might crash

Made Debugger's Video Memory tab show correct resource paths.
The Icons are still missing but that is due to the get_icon(type, "EditorIcons") for type = "Texture" being missing. Adding that icon would fix it.

The two POSIX style crash handlers (OSX and X11) now remove their signal
handlers when they are destroyed.
Additonally if they are called while no OS singleton is set, they will
simply abort(). This should not happen now that they remove themselves,
but if a future change seperates OS object and crash handler lifetimes,
this may be easier to report/debug than hanging on SIGSEGV.
