fix(material/select): close panel on detach output event

[DavidACCarvalho]

Enable detection of the detach output event on the panel of the mat-select component. This ensures that when CloseScrollStrategy is set via MAT_SELECT_SCROLL_STRATEGY, the panel correctly closes on scroll, updating the panelOpen property to false.

Fixes #30620

@DavidACCarvalho can you rebase the PR against the latest main branch? We had to move some things around that are conflicting when I try syncing the changes into our internal repository.

It looks like the select.html got reformatted again.
