arm: add armv9-a architecture to -march
Update also include:
+ New value of Tag_CPU_arch EABI attribute (22) is added.
+ Updated missing Tag_CPU_arch EABI attributes.
+ Updated how we combine archs 'v4t_plus_v6_m' as this mechanism
have to handle new Armv9 as well.
Regression tested on `arm-none-eabi` cross Binutils and no issues.
