Fix various fetch/response/request tests (#2416)

* fix most fetch tests, skip a few

* fastGet, toValueGC, and invalid init

* bigint unreachable, range error, log process as process

* remove extra fetch_headers

* remove js_type parameter, check isObject()

* throw invalid mime type error, use enum literal

* switch back to promise rejection

* RangeError pascal case
