 qemu: fix +gl build with clang 15 and later

 ui/egl-helpers.c passes an EGLNativeDisplayType straight to
 eglGetPlatformDisplayEXT(), whose second parameter is void *.  That
 typedef is only a pointer on window systems that define a native display
 type; Mesa's surfaceless configuration, which is what macOS uses, makes
 it an int.  clang 15 promoted -Wint-conversion from a warning to an
 error, so the gl variant now fails to build outright:

     ui/egl-helpers.c:531:54: error: incompatible integer to pointer
       conversion passing 'EGLNativeDisplayType' (aka 'int') to parameter
       of type 'void *'

 Casting through uintptr_t is correct whether the typedef is an integer or
 a pointer, so the patch needs no version or platform guard.  It is
 registered inside the gl variant rather than at the top level, since
 ui/egl-helpers.c is only compiled when opengl is enabled.

 Reproduced and verified on macOS 26.6.1 arm64 with Apple clang 21: the
 original construct is a hard error against the installed epoxy headers,
 the patched one compiles cleanly under -Wall -Wextra, and a full
 qemu +gl install then succeeded.  No revision bump, since the generated
 code is unchanged for anyone whose compiler accepted the old form.
