Timer: Add usePageVisibilityAPI ctor parameter.

[Mugen87]

Related issue: #30497

Description

As requested in #30497, the PR introduces an optional ctor parameter that controls the usage of the Page Visibility API to avoid large time delta values in inactive tabs. The default is true but it can be set to false if this mechanism isn't wanted.

Hmm, how about something like this?

const timer = new Timer();
timer.connect( document );
timer.disconnect();

To avoid the #20575 issue...

Since we use the connect()/disconnect() pattern in all controls now, I think we can adapt the same approach in Timer as well 👍 .
