Vishwath Mohan 83d9f71cc5 Allow custom ar flags to be set.
Adds the ability to set custom flags for ar in Soong, similar to how
they can currently be set for make.

Bug: 36290748
Test: sanitize.go is able to correct set custom ar flags for CFI. CFI
enabled Soong components build and boot without issue.
