bf_usd is a bit slow to build, and most time is spend on the front end
of the compiler parsing USD's headers.

this change enables pre-compiled headers for the most expensive
headers to parse.

When building bf_usd single threaded with -j1 (for accurate measurements)

before Wall time:      0h 4min 30sec 931 ms 504299 ns
after  Wall time:      0h 0min 50sec 808 ms 24399 ns
