[Python] Adjust type patterns#4541

Conversation
This commit teaches Python to scope identifiers `variable.other` instead of `support.class` if they contain underscore to reduce chance of false positives. Note: Classes still may start with underscore.
This is a formal change, not affecting syntax behavior.
Scope single uppercase letter tokens, variable.other. May help to reduce false positives and is not semantically wrong with regards to generics.

Addresses #4540
This PR restricts which tokens are scoped
support.class.Scope tokens as type only, if they
PascalCaseor_PascalCasewithout underscores in between.3. do not end with uppercase letterSingle char upper case tokens are now scoped
variable.other, which is probably an appropriate scope for "type variables" in generics as well.It would be possible to keep them scoped
support.typein type annotations with further adjustments to related contexts. Those currently use normal expression rules, which causes some ambiguities to resolve - especially with regards toafter-expressioncontext.
