fix(chromium): detach from shared workers (#18976)
This prevents shared workers from stalling upon restart.

We receive `Inspector.targetCrashed` and
`Inspector.targetReloadedAfterCrash` events that assume
`Runtime.runIfWaitingForDebugger` from any attached client. It is easier
and more stable to just detach from shared workers, because we do not
inspect them.

For service workers, we should actually issue
`Runtime.runIfWaitingForDebugger` in such cases, because we attach to
them.

Fixes #18932.
