Update TinySTL (attempt 2).

[mcourteaux]

A better-tested updated version of TinySTL. Replaces #340.
This library was in a very buggy state, so I made my own fork of it, patched all the issues, and made a PR there (mendsley/tinystl#27).

I added some extra tests that were present in the tinystl repo, but not yet in the bx testsuite. All tests are passing. This time I did test the examples, and I don't get any crashes.

Also includes a small update-script to pull it the sources from the original repo and replace all #include <TINYSTL/xxx> with #include <tinystl/xxx> using sed.

Idk if there are cool tricks in Github to rewrite git history as if my first PR was never merged (instead of merged, reverted, and then this merged).

There is issue with MSVC builds:

Instead updating the whole thing, you should fix whatever you need to fix in bx.

It's not an error. Was a type-cast warning elevated to error-level. Fixed in #342, checked the CI bots now for warnings. Good to know that's a thing. Real issue here is that bx is compiled with lower warning-to-error-escalation settings than bgfx. Therefore CI test on bx passed, but failed on bgfx.

It shouldn't... Where is the difference?

On the one hand (warning as error in bgfx):
https://github.com/bkaradzic/bgfx/actions/runs/13058550303/job/36435625648#step:6:3202

D:\a\bgfx\bgfx\bx\include\tinystl\string.h(251,12): error C2220: the following warning is treated as an error [D:\a\bgfx\bgfx\bgfx\.build\projects\vs2022\examples.vcxproj]

On the other hand (bx):

Warnings not even printed, for a test string_test.cpp using tinystl::string:
https://github.com/bkaradzic/bx/pull/341/files#diff-c5446f4c1753d974786291fb72e312a4cf3382866566436b403c088f781cb052R642

Perhaps the bx test suite doesn't have the same warnings enabled?
