i386: Do GNU2 TLS address computation in ptr_mode

Since GNU2 TLS address from glibc run-time is in ptr_mode, we should do
GNU2 TLS address computation in ptr_mode and zero-extend result to Pmode.

gcc/

	PR target/93319
	* config/i386/i386.c (ix86_tls_module_base): Replace Pmode
	with ptr_mode.
	(legitimize_tls_address): Do GNU2 TLS address computation in
	ptr_mode and zero-extend result to Pmode.
	*  config/i386/i386.md (@tls_dynamic_gnu2_64_<mode>): Replace
	:P with :PTR and Pmode with ptr_mode.
	(*tls_dynamic_gnu2_lea_64_<mode>): Likewise.
	(*tls_dynamic_gnu2_call_64_<mode>): Likewise.
	(*tls_dynamic_gnu2_combine_64_<mode>): Likewise.
