aarch64: Fix target/optimize option handling with transiting between O1 to O2
The problem here is the aarch64 backend enables -mearly-ra at -O2 and above but
it is not marked as an Optimization in the .opt file so enabling it sometimes
reset the target options when going from -O1 to -O2 for the first time.
Build and tested for aarch64-linux-gnu with no regressions.
PR target/116065
gcc/ChangeLog:
* config/aarch64/aarch64.opt (mearly-ra=): Mark as Optimization rather
than Save.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/sve/target_optimization-1.c: New test.
