refactor(ivy): remove styling state storage and introduce direct style writing (#32591)

Browse Source 
This patch is a final major refactor in styling Angular.

This PR includes three main fixes:

All temporary state taht is persisted between template style/class application
and style/class application in host bindings is now removed.
Removes the styling() and stylingApply() instructions.
Introduces a "direct apply" mode that is used apply prop-based
style/class in the event that there are no map-based bindings as
well as property collisions.
