Make blueline use generic arch variant

This makes the system image more generic. The intent is so to
add another set of flags to allow the vendor partition to compile with
more specific flags once the build system can support that.

Only blueline for now, so that we can compare perf to crosshatch.

Bug: 120773446
Test: various benchmarks
Test: boot blueline
