Tracking issue: Fix CA2213: Disposable fields should be disposed and remove suppressions.

In #15805, each rule violation will be suppressed like so:

#pragma warning disable CA2213 // Disposable fields should be disposed
        private Timer _timer;
#pragma warning restore CA2213 // https://github.com/PowerShell/PowerShell/issues/15803

We need to review every case and either fix as bug or suppress with description why it is not bug and maybe add more info in (XML) docs.

Some of the rule violations may be false positives/unfixable/breaking change if the disposable has been injected via a property, etc.

TODO: after reviewing and fixing all violations listed here, please re-open #15805 to enable the CA2213 rule so as to make sure no violations in future.
