chore(grouping): Add unsafe-eval and unsafe-inline grouping test inputs

[lobsterkatie]

This adds two new grouping test inputs, to show how we handle CSP reports with unsafe-eval and unsafe-inline violations, which are cases we don't currently cover with our grouping tests.

Note that there are two bugs which currently affect how we handle such inputs:

• We don't currently recognize such reports for grouping metadata purposes (this is very soon to be fixed), which is why for now they're being recorded in the metadata snapshots as being grouped by an unknown method.

• We handle such reports backwards at the ingest level, marking events which aren't either unsafe-eval- or unsafe-inline-type violations as one or the other. (Unclear how soon this will be fixed, as it went undetected for five years and no one has yet complained about it.) For now, the input data includes the necessary values to trigger the relevant handlers, but each also includes a TODO so that it can be updated once the underlying bug is fixed. (See [CSP] Incorrect script-src handling relay#4323 and [CSP] Update script-src handling once relay bug is fixed #81531.)
