Android: enable noreturn and returns_nonnull attributes

Android: enable noreturn and returns_nonnull attributes

Commit 94ca8e04adf6 ("spirv: Add vtn_fail and vtn_assert helpers") broke
Android builds which have -Werror enabled with the following errors:

external/mesa3d/src/compiler/spirv/spirv_to_nir.c:272:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]
external/mesa3d/src/compiler/spirv/spirv_to_nir.c:810:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]
...

The problem is the noreturn attribute is not enabled and we to define
HAVE_FUNC_ATTRIBUTE_NORETURN.

Auditing src/util/macros.h, we're also missing
HAVE_FUNC_ATTRIBUTE_RETURNS_NONNULL and HAVE_FUNC_ATTRIBUTE_WARN_UNUSED_RESULT,
so add them too.
