Wesley Wigham 5353475fce Always collect type and symbol baselines (#18621) 
* Always generate type & symbol baselines

* Accept changed shadowed baselines

* Accept brand new type and symbol baselines

* Allow `getTypeAtLocation` to return undefined in the type writer

* Accept baselines which had missing type information

* Bind container for dynamically names enum members so they may be printed

* Accept type/symbol baselines for enums with computed members

* First pass at reducing typeWriter memory overhead

* Use generators to allow for type and symbol baselines with no cache

* Accept new baselines for tests whose output was fixed by better newline splitting

* Hard cap on number of declarations printed, cache declaration print text

* handle differing newlines better still to handle RWC newlines

* Lower abridging count, accept abridged baselines

* Limit max RWC error output size, limit RWC type and symbol baseline input size

* Move skip logic into type and symbol baseliner to streamline error handling

* Accept removal of empty baselines

* Canonicalize path earlier to handle odd paths in input files

* Do canonicalization earlier still, also ensure parallel perf profiles for different targets do not trample one another

* No need to pathify again
