[ML] Angular based pages no longer use $q as the default Promise

Describe the bug:
For every angular based page in ML, we replace window.Promise with $q, this allows us to share Promise based util functions between angular and react code without needing to explicitly call $applyAsync when a resolving promise has to update the page.
This happens in a resolver, added to the routing stage of each page, and so happens before the page has fully loaded.

A recent change in core kibana undoes this change, reverting Promise back to a non-angular version after these resolvers have been run.
#25711

This causes angular based pages to not update correctly when actions are performed or data has been loaded via a Promise

Steps to reproduce:

1. Open the Single Metric Job creation page
2. Refresh the page (F5/cmd-R)
3. Attempt to create a new job. The chart loading spinner doesn't disappear.

Expected behavior:
Page should work as expected
