Add a IsInstrumentationRuntimePresent SB API

[kubamracek]

Summary

This adds an SB API into SBProcess:

bool
SBProcess::IsInstrumentationRuntimePresent(InstrumentationRuntimeType type);

which simply tells whether a particular InstrumentationRuntime (read "ASan") plugin is present and active.

Looks good to me.
