fix precompile process flag propagation (#56214)

CacheFlags could get set, but were never propagated to the target
process, so the result would be unusable. Additionally, the debug and
optimization levels were not synchronized with the sysimg, causing a
regression in pkgimage usability after moving out stdlibs.

Fixes #56207
Fixes #56054
Fixes #56206
