Buck: Mark auto value annotation processors as safe

Browse Source 
This diff: [1] allows marking certain annotation processors as "safe"
via a `.buckconfig` item, and then reuses class loaders when only
"safe" annotation processors are involved.

This results in a 50% reduction in annotation processing time (42%
reduction in `javac` time) in a large test build, as measured by Buck
tracing.
