[TypeScript] Add support emmet for typescript react (tsx) files

[okian]

Please add emmet features for typescript react

Good idea. Need to explore whether we can just take over the tab key in .tsx files as we do in the other file types.

+1 I would like to have emmet also for JavaScript React (in *.jsx files)

It is now enabled in both jsx and tsx files and for both the jsx filter is used that converts class -> className

Apparently the new wisdom is to not use .jsx file extensions, but rather to use .js instead. Can you enable this same functionality for .js extensions too please?
