arm: add armv9-a architecture to -march

Browse source 
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.
