Subject: [PATCH] feat: add bottom sheet component (#9764)

* Adds an initial implementation of the new `MatBottomSheet` service that allows users to display component-based or template-based bottom sheets.
* Sets up the various boilerplate and infrastructure necessary for a new component.

Note: this is an initial implementation that has the necessary functionality, styles and accessibility. More docs, examples and touch gestures will be added in a follow-up.
