types: cover the tests with root tsconfig.json

[huozhi]

We're using react automatic transform now, tsconfig.json jsx will be aligned as react-jsx. Some tests files are showing 'React' refers to a UMD global, but the current file is a module if there's no react import, cause they're not being covered by jsx config in tsconfig.json. Update the jsx config in root tsconfig.json to cover test ts/tsx files.

Adding a new test/tsconfig.json to resolve the modules and parsing jsx correctly

Closes NEXT-1859
