Revitalize test262 runner #1847

Closed kriskowal closed 7 months ago

refs: https://github.com/endojs/endo/issues/870 closes: #812

Description

We have not been running test262 since we migrated from tape to ava for lack of a suitable runner. We have deeper needs for a test262 runner now since we would like to verify parity between node+ses and XS. This change pivots the runner from a bespoke implementation to bterlsen’s test262-harness which supports node and xs. Then, by way of demonstration, we bring in XS tests and get one of them passing in SES.

attn @phoddie, this is the PR that’s introducing eshost based SES parity testing. It requires running our shim in a prelude to every SES test, so it’s slow, but a place to start. This also gives us a place to stand to carve out a leaner SES shim specific to XS.
