[gas][arm] Set context table for '.arch_extension'
This patch fixes .arch_extension behaviour.
Currently, context table for '.arch_extension' is only set while
"-march" processing, but it is not set while .arch processing,
so following code is rejected
.syntax unified
.thumb
.arch armv8.1-m.main
.arch_extension mve.fp
unless -march=armv8.1-m.main is given.
