feat(tabs): add input to opt out of pagination

[crisbeto]

Currently the tabs pagination works automatically by measuring the size of the tab header to figure out whether to show pagination. This measuring can be expensive because it triggers a page layout and might not necessarily be required if the page won't have enough tabs to paginate through.

These changes add an input and an option to the injection token to allow consumers to opt out of the pagination, if they know that they won't need it.

Fixes #17317.

LGTM

Could you change this to use coerceBooleanProperty in a follow-up?

I see that you just added the pr: merge ready label, but the following checks are still failing:
     status "ci/circleci: api_golden_checks" is failing

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.
