Add lookup tables to DiagnosticsManager to speed up diagnostic clearing

[markwpearce]

TBH, I'm not sure if this will speed up validation. However, there are many times in the validation process when the Diagnostic Manager needs to clear all diagnostics based on scope, file, tag, etc. Previously, this was done by looping all diagnostics, so if there are lots, it probably went slower and slower. This change should make it much more quick to find the diagnostics that need to be cleared.

Also added some more fine-grained Scope Validation metrics that are printed out with log-level debug:

Might be something to address later, but array.includes will basically do a sequential loop over every element in the array. Could be pretty expensive. Is there any chance we could change the storage of these items into Set instead? Then the .has will be a hash lookup (much faster). But adding to those sets is slightly slower than arrays.

I'm not sure the context here, just a thought.
