  [ctxprof] Override type of instrumentation if `-profile-context-root` is specified (#128940)

This patch makes it easy to enable ctxprof instrumentation for targets where the build has a bunch of defaults for instrumented PGO that we want to inherit for ctxprof.

This is switching experimental defaults: we'll eventually enable ctxprof instrumentation through `PGOOpt` but that type is currently quite entangled and, for the time being, no point adding to that.
