Add initial test trace outputs

[ijjk]

This adds uploading test traces from playwright and .next/trace when a test fails to allow investigating flakes that aren't able to be reproduced easily. This also updates the swc test for the new expected output.

The playwright traces can be viewed with yarn playwright show-trace ./path/to-playwright-trace.zip and the next-trace file can viewed with jaegar or ./scripts/trace-to-tree.mjs.
