On Windows, cmake/xxd.py generates text files with \r\n eol.
Because the in-repo files were stored with \n, and git considered
them as binary files, they were always considered out of date.
An alternative fix could be to let xxd.py generate binary files with \n.
But a .gitattributes file should also avoid people accidentally
converting line endings.
CMake's SDL_build_config.h force disables HAVE_STDIO_H when buiding
winrt in non-libc mode.
Becase CreateFileEx is not available in UWP mode, use CreateFile2
instead.
main features:
- No more sdl-build-options/sdl-shared-build-options/sdl-global-options
- Dependency information is stored on SDL3-collector for sdl3.pc
- Use helper functions to modify the SDL targets;
- sdl_sources to add sources
- sdl_glob_sources to add glob soruces
- sdl_link_dependency to add a link dependency that might also
appear in sdl3.pc/SDL3Config.cmake
- sdl_compile_definitions to add macro's
- sdl_compile_options for compile options
- sdl_include_directories for include directories
They avoid repeated checks for existence of the SDL targets
- A nice feature of the previous is the ability to generate
a sdl3.pc or SDL3Config.cmake that describes its dependencies
accurately.
various:
- remove duplicate libc symbol list
- add CheckVulkan
- remove unused HAVE_MPROTECT
- add checks for getpagesize
This fixes the following errors when a dll attempts to link to SDL3::SDL3-shared:

On platforms where time_t is a signed 32-bit integer, most notably i386 Linux,
various functions stop working when dealing with a timestamp
beyond January 2038.
glibc has an opt-in mechanism that redefines time_t to be 64-bit,
and correspondingly increases the size of all system data
structures that contain a time_t, such as struct timeval and struct stat.
This is necessary to allow timestamps beyond January 2038 to be represented;
as well as things that obviously deal with timestamps, this affects functions
like stat(), which will fail with EOVERFLOW if asked to inspect a file whose
correct timestamp does not fit in time_t. This in turn can cause unexpected
problems for "filesystem APIs" of the form "if /run/foo exists, then ..."
when accessed by 32-bit code, if the check for existence is done with stat()
rather than access().
Using 64-bit timestamps in glibc is an opt-in and not the default, because
if done carelessly it can change libraries' ABIs. However, SDL mostly doesn't
use system headers or types in its own headers. I

__attribute__((target(xx))) is not supported by LoongArch64.
The following warning is emitted:
target attribute is not supported on this machine [-Wattributes]
The /Gs argument controls the number of bytes that local variables
can occupy before a stack probe is initiated.
By setting it to a huge value, no calls to __chkstk are inserted.
This change is needed for the classic Intel C compiler to build SDL
with -DSDL_LIBC=OFF.
