fix(babel-parser): avoid state.clone() to clone the whole token store (#11029)

Browse Source 
* fix(babel-parser): avoid state.clone() to clone the whole token store

Fixed the performance issue on large input when turned on option {tokens: true} and typescript plugin which uses quite a few state.clone().

* test(babel-parser): turn on 2 typescript tests with tokens:true

The output.json is generated by old master to make sure no regression.

* fix(babel-parser): avoid duplicated tokens trapped by mainly typescript/flow plugins

* test(babel-parser): update output.json to latest master result

* chore(babel-parser): improve performance by storing tokensLength in state
