Improve highlighting of identifiers

[tobil4sk]

This allows customisation for how variable/member identifiers are highlighted and links them to Identifier by default.

Vim docs: Identifier any variable name.

should Prop be linked to Identifier? It will make both option and field in expression likeoption.field highlighted as identifiers.

Also, can you paste a screenshot for the change? thanks

Vim only has Identifier, so it doesn't distinguish between variables and fields. Currently, option and field already look the same since both are unlinked.

I noticed on NeoVim the original coloring is more diverse and differentiated. The updated syntax highlighting is not too clear. Say, the option.field(arg) is all green color, but the original highlight has two colors.

I can change it to unlink typescriptProp if this is preferred:

As long as typescriptProp and typescriptIdentifierName are not set as transparent, then this gives more control for custom themes to differentiate them.
