Revert "Support dynamic refresh of WebRtcEventLogCollectionAllowed policy"

This reverts commit 7dae0f6307b6ffc38b69faa9340d2ef7d298aabd.

Reason for revert: As per the Findit comment, this introduced flakiness.

Original change's description:
> Support dynamic refresh of WebRtcEventLogCollectionAllowed policy
> 
> Add suport for dynamic refresh of WebRtcEventLogCollectionAllowed:
> 1. If the policy was disabled before, and becomes enabled,
>    subsequent calls to StartRemoteLogging() will succeed (barring
>    unrelated issues), even for peer connections created while the
>    policy was disabled.
> 2. If the policy was enabled before, and becomes disabled:
>    a. Peer connections associated with the profile reject
>       calls to StartRemoteLogging().
>    b. Active logs (associated with the profile) are stopped,
>       and those log files deleted.
>    c. Pending log files (associated with the profile) are deleted.
>    d. If a log file associated with the relevant profile is
>       currently being uploaded, the upload will be cancelled,
>       and the file deleted.
