…exitWithCleanup logic As of 2024-10 and chrome v130, there is a problem where Chrome client `close()` function won't return correctly, skipping the normal code part of closing a chromium process started. So processes were not killed. Now those browser processes are added to the same cleanup handler used by `execProcess()` logic so that in case of something going wrong, they are killed and closed at last resort when Quarto exists.

Follow up on #11135 and #11187 as they surfaced a problem where Chromium processed where not closed after rendering.
The real issue is there
quarto-cli/src/core/cri/cri.ts
Lines 129 to 130 in c8a3e7c
where somehow
await client.close()does not return and sobrowser.close()never happens. This was confirmed by debugging interactively in VSCODE on Windows.This PR is not solving the issue which is tracked at #11196 - it is only improving current logic for 1.6 releases to make sure we do clean after ourselves in all cases, like we do with other processed.
So for that aim, this PR adds
browserDeno process to the same cleanupHandler for processes for quartoexitWithCleanup()logic. This cleanupHandler has all processes started withexecProcess()already, but we can't useexecProcess()here as we want to start the process in background, do HTML printing, then close.
