[scons multi_isa] extend multi_isa build to support armv8-a march
This change adds support for multi isa build with armv8-a as the
base micro architecture. To enable this, use 'arch=armv8a' and 'multi_isa=1'
build flags during scons build. This build option doesn't include
fp16 vector arithmetic. To include fp16 vector arithmetic, use 'arch=armv8.2-a'
and 'multi_isa=1' build option.
