Add test262 setup patches to QuickJS

Test262 are 70k+ Javascript conformance tests [1].

QuickJS has its own test runner but unfortunately there is not automatic
bootstraping and they run by hand. There is an upstream PR [2] to add these
tests to run there but until that happens we can patch our own QuickJS with.

This particular commit doesn't run the tests just patches the necessary updates
for bootstrapping and some timeout tweaks to fix some flakes.
