LSP: Allow for an LSP extension match on any suffix, not just filename and ext

[nathansbradshaw]

Angular shares file extensions with html and ts. It is conventional for an angular file to follow the format *.component.html or *.component.ts. This PR allows LSP to add an optional Language detection field called path_regex that can be used to sort out duplicate Languages, such as in the case of angular files.

Release Notes:

• Added Path_Regex option for LSP configs

I think we may just want to extend path_suffixes to handle these cases.

Adding a separate configuration option feels weird.

I agree, it seems like a path_suffixes need to not just match against the extension and the filename, but rather split the filename on a ., and check if any suffix of that split list matches the entry.
