  [clang] Improve diagnostics for `__builtin_align` builtins with floating/member pointer operands (#192650)

Improve diagnostics for `__builtin_align_up`, `__builtin_align_down`,
and `__builtin_is_aligned` when the first operand has an invalid type.

Clang already emits `err_typecheck_expect_scalar_operand` for
unsupported operands, but the message is generic. This patch adds
follow-up notes to clarify three common invalid cases:

* floating point operands (“floating point types are not allowed here”)
* C++ member pointer operands (“member pointers are not allowed here”)
* plain-function-pointer ("function pointers are not allowed here")
