This patch adds `LLDBLog::InstrumentationRuntime` as a log channel to provide an appropriate channel for instrumentation runtime plugins as previously one did not exist. A small use of the channel is added to illustrate its use. The logging added is not intended to be comprehensive. This is primarily motivated by an `-fbounds-safety` instrumentation plugin (https://github.com/swiftlang/llvm-project/pull/11835). rdar://164920875
