Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

#ifdef TEST_NATIVE_X11
Updated SDL_syswm.h for SDL 3.0 * The header is no longer dependent on SDL build configuration * The structures are versioned separately from the rest of SDL * SDL_GetWindowWMInfo() now returns a standard result code and is passed the version expected by the application * Updated WhatsNew.txt and docs/README-migration.md with the first API changes in SDL 3.0

Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594
