[estree] update with latest spec changes (#43103)

Browse Source 
* [estree] support async for-of

See https://github.com/estree/estree/blob/master/es2018.md#statements

* [estree] support spread properties

See https://github.com/estree/estree/blob/master/es2018.md#expressions

* [estree] support rest property patterns

See https://github.com/estree/estree/blob/master/es2018.md#patterns

* [estree] add support for ImportExpression

See https://github.com/estree/estree/blob/master/es2020.md#importexpression

* [es2020] add support for BigInt literals

See https://github.com/estree/estree/blob/master/es2020.md#bigintliteral

* Revert "[es2020] add support for BigInt literals"

This reverts commit 47134accb91cf73307d434f57acf97bc0328f39e. Supporting bigint would require TS 3.2 which requires dependency changes that can probably wait? 🤷‍♂️

* [estree] add new expression type to Union

* narrow express node by ImportExpression
