Accept baseline diffs, round 2

[ahejlsberg]

Second batch of accepted baseline differences.

[Copilot]

Pull request overview

This PR adds a second batch of “accepted baseline” diff artifacts under testdata/baselines/reference/submoduleAccepted/compiler/, recording known, intentionally-accepted output differences between this port and the upstream TypeScript baselines.

Changes:

• Add newly accepted .diff baseline files for compiler test outputs (types/symbols/errors and some .d.ts/.js emit snapshots).
• Update accepted diagnostics baselines for a variety of error reporting/elaboration/related-span formatting cases.
• Update accepted type printer / symbol printer baselines for overload/type-parameter printing and JS/TS interop scenarios.
