[clang] [Clang][AArch64] Use 'uint64_t*' for _arm_get_sme_state builtin. (PR #95982)

[Sander de Smalen via cfe-commits]

https://github.com/sdesmalen-arm created https://github.com/llvm/llvm-project/pull/95982

Depending on the platform, the parameter for __arm_get_sme_state requires a `unsigned long long*` instead of a `unsigned long*`.

>From ASTContext.cpp:

  case 'W':
    // This modifier represents int64 type.
