ShuangLiu1992 4eb6f8ebb2 platform: bridge legacy lowercase emscripten version macros (#397) ...

emscripten <= 4.0.23 only defined the lowercase forms (`__EMSCRIPTEN_major__`,
`__EMSCRIPTEN_minor__`, `__EMSCRIPTEN_tiny__`) in `<emscripten/version.h>`.
Starting with 4.0.24 (PR emscripten-core/emscripten#26180), uppercase
became primary and lowercase was kept as deprecated aliases.

bx PR #374 switched all references to the uppercase form, which is the
right forward-looking direction — but it leaves users on emsdk <= 4.0.23
unable to build, because `__EMSCRIPTEN_MAJOR__` is undefined there and
the preprocessor expression `(__EMSCRIPTEN_MAJOR__ * 10000 + …)` evaluates
to 0. That tanks `BX_PLATFORM_EMSCRIPTEN`, which tanks `BX_PLATFORM_POSIX`,
which makes `bx/src/os.cpp` skip its `<time.h>` / `<sched.h>` includes,
which causes the build to fail on `unknown type name 'timespec'`.

Add a small bridge: if the uppercase macros aren't defined but the lowercase
ones are, alias the uppercase forms to lowercase. The rest of bx continues
to use uppercase uniformly. Newer emsdk versions are unaffected (the bridge
block is skipped because uppercase is already defined).
