This commit prepares GCC for full SVE2.2 and SME2.2 support by adding essential definitions. It introduces TARGET_* constants based on ISA flags and new match_test definitions to control instruction pattern availability. The update also includes new effective-target checks in lib/target-supports.exp to verify SVE2.2 support in both hardware and the toolchain.
