[WIP] Improve Jest, TypeScript and webpack(er) configs

[vojtechszocs]

Jest config

• differentiate between setupFiles vs setupTestFrameworkScriptFile in order to load enhancers like angular-mocks
• set moduleFileExtensions to cover .js(x) and .ts(x) files
• provide ManageIQ.angular.app for testing purposes
• add spyOnDeeply test helper, this will be needed in a follow-up PR

TypeScript config

• use "jsx": "react" in compiler options so that JSX gets compiled to JS code containing React.createElement calls

webpack(er) config

• add .tsx to file extensions in webpacker.yml
• the vendor chunk is no longer empty - it now contains webpack runtime and all code that comes from 3rd party modules (anything that comes from node_modules)

It's important to load vendor before any *-common chunks, as it contains webpack runtime (e.g. the webpackJsonp global) as well as common 3rd party modules.

Extracted the "clearly good" bits to #3576 and #3575. (And #3577.)

If you can remove those and remove the non-changes (adding an example comment, removing commas from config), this will nicely simplify to a jest-only PR :).

(I have no real objections to the jest-related changes, it's just this was doing too many unrelated things, and unmergeable, so I split off the stuff we need in first :).)

Thanks @himdel - I agree, I'll take out the stuff that was extracted and update this PR.
