 When trying to build tree-sitter-cpp with GCC 12, the build fails and this
 error appears during the process:
 {{{

 scanner.c: In function 'tree_sitter_cpp_external_scanner_serialize':

 }}}

 As `static_assert` is a feature introduced in C11, it would seem that the
 problem comes from the compiler not being in C11 mode, but adding
 `compiler.cxx_standard 2011` or `compiler.c_standard 2011` doesn't help,
 and neither does `configure.cflags-append -std=c11`. However, if the
 `static_assert` is manually deleted from the source code, or `-std=c99` is
 passed in, the code compiles fine. Additionally, changing the
 `static_assert` to `_Static_assert` also allows it to build without issue.

 This bears a striking similarity to #64113, and in that ticket, it appears
 that upstream decided to change `static_assert` to `_Static_assert` for
 better compatibility. Assuming this bug also affects the same versions of
 Clang/GCC as the xxHash one does, it might be reasonable to add a patch
 that applies the same change to tree-sitter.
