Bug 1775424 - Part 1: Impl import.meta.resolve() on browser. r=jonco,yulia

Browse Source 
Define 'resolve()' function on import.meta object on browser.

Add mochitests for import.meta.resolve, as some of the wpt tests for
import.meta.resolve cannot be run due to some bugs in wpt testing framework.
