Shahbaz Youssefi 6f80f0f037 Translator: Clean up the compile flag passing interface
Historically, compile flags were sent to the translator as a bitmask.
Recently, we were getting close to running out of bits.  Additionally,
direct-to-metal work had started to introduce constants to be passed to
the translator, which were misplaced in ShBuiltInResources and Caps.
Recent work on Pixel Local Storage adds even more constants, aggravating
the situation.

In this change, the interface to passing compile flags is reworked.  A
struct is passed (instead of a bitmask) that has one bit for each flag.
This can be indefinitely extended.  Additionally, the constants needed
by metal and PLS are also placed in this struct.  In turn, the backends
can set these options directly, and don't have to hack them into Caps to
further get hacked into ShBuiltInResources.
