Nathan Chancellor 7a618ca9b9 init/Kconfig: Require a release version of clang-22 for CC_HAS_COUNTED_BY_PTR 
Commit 150a04d817 ("compiler_types.h: Attributes: Add __counted_by_ptr
macro") used Clang 22.0.0 as a minimum supported version for
__counted_by_ptr, which made sense while 22.0.0 was the version of
LLVM's main branch to allow developers to easily test and develop uses
of __counted_by_ptr in their code. However, __counted_by_ptr requires a
change [1] merged towards the end of the 22 development cycle to avoid
errors when applied to void pointers.

  In file included from fs/xfs/xfs_attr_inactive.c:18:
  fs/xfs/libxfs/xfs_attr.h:59:2: error: 'counted_by' cannot be applied to a pointer with pointee of unknown size because 'void' is an incomplete type
     59 |         void                    *buffer __counted_by_ptr(bufsize);
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is disruptive for deployed prerelease clang-22 builds (such as
Android LLVM) or when bisecting between llvmorg-21-init and the fix.

Require a released version of clang-22 (i.e., 21.1.0 or newer) to
enabled __counted_by_ptr to ensure all fixes needed for proper support
are present.
