fix(windows): avoid disabling Keyman when speech recognition starts

Fixes #4965.

When speech recognition is enabled, it sometimes activates after a
Keyman keyboard is selected. This would cause Keyman to think it is
being deactivated. We needed to check in
`CKMTipTextService::OnActivated` that it was a keyboard-type TIP that
was being activated, and only deactivate the Keyman hooks in that
situation.

This commit also adds a little logging helper function, and removes an
unused variable `guidActiveProfile`.
