rs6000: Corrections for the AES builtins for powerpc

This patch fixes few implementations issues for the AES builtins in
powerpc in documentation, testcases and builtin definition.

2026-07-09  Avinash Jayakar  <avinashd@linux.ibm.com>

gcc/ChangeLog:
	* config/rs6000/rs6000-builtins.def: Move AES builtins to future-vsx
	stanza.
	* doc/extend.texi: Add subheading for AES builtins.

gcc/testsuite/ChangeLog:
	* gcc.target/powerpc/aes-builtin-1.c: Add future_compile_ok and lp64
	testsuite directive.
	* gcc.target/powerpc/aes-builtin-2.c: Add future_compile_ok and lp64
	testsuite directive.
	* gcc.target/powerpc/aes-builtin-3.c: Add future_compile_ok and lp64
	testsuite directive.
