aarch64: Fix PCH for sve builtins [PR123457]

The problem here is function_table was not in the GGC memory space and not
streamed out. So even though the builtins were reloaded, function_table was
a nullptr as it was not reloaded.

Also noticed initial_indexes should be marked with GTY so it is reloaded correctly
from PCH.

Built and tested for aarch64-linux-gnu.

	PR target/123457
gcc/ChangeLog:

	* config/aarch64/aarch64-sve-builtins.cc (struct registered_function_hasher):
	Change base class to ggc_ptr_hash.
	(initial_indexes): Mark with GTY.
	(function_table): Likewise.
	(handle_arm_sve_h): Allocate function_table from ggc instead of heap.
