"static const" being treated as constant in C is an extension that is not always supported, so use defines instead.

This PR adds support to the cmake build scripts so to allow building SDL with the Tiny C Compiler (tcc).

TinyCC supports the subset of C99 used by SDL and will complete the build once the --version-script linker flag is removed. The changes have been tested with various build configurations, including X11 and Wayland, and using tcc version 0.9.28rc 2025-10-27 mob@f4e01bfc on x86_64 Linux.

Fixes #13484.

…s are toggled

An event flush while a window is being hidden may try to toggle the window borders. Don't poll the mapping state when toggling borders if the window is in the process of being hidden, or the window may already be unmapped, and the wait loop will hang forever.
