[Target] Add Target Parser for Arm(R) Cortex(R) A-Profile CPUs

[Mousius]

This implements an initial Target Parser which aims to consolidate architecture feature detection from a few different places:

• https://github.com/apache/tvm/blob/d2db9cb0d839e32778f461b77e59f6418282a511/python/tvm/topi/arm_cpu/arm_utils.py#L24-L70
• https://github.com/apache/tvm/blob/02fbaf0ed9120a8f95155e63de42459f230584aa/python/tvm/relay/qnn/op/legalizations.py#L350-L359
• https://github.com/apache/tvm/blob/b542724873140bb051492530d97a78b9b7b7983d/python/tvm/relay/op/strategy/arm_cpu.py#L232

A further patch will remove all of the above and replace usages with the .features map.
