Sheet gravity is intended to be set once at setup before the sheet is shown; sheet gravity changes are not supported at runtime and will cause an IllegalStateException.
Also refactored modal sheet demo to recreate the sheet every time it's shown, which allows the sheet gravity changes to take effect for modal sheets.

Standard and coplanar side sheets now support sliding and dragging from the left side, as well as automatic RTL mirroring when `layout_gravity` is set to `start` or `end`. Change the sheet edge by setting `layout_gravity` on the side sheet view in XML or programmatically.

This adds an accessibilityPaneTitle that is spoken by TalkBack on API levels 19 and later.
In order to trigger the accessibilityPaneTitle event, it was necessary to add a visibility change when the sheet is expanded and hidden. The sheet now is INVISIBLE at STATE_HIDDEN and VISIBLE at all other states.
Also removed the code to switch focus to the sheet on expansion in favor of this approach to align with TalkBack's APIs.

Added logic for an innerMargin to SideSheetBehavior and delegates and incorporated innerMargin into the sheet offset calculations to account for the extra spacing and avoid a jump when dragging the sheet to STATE_EXPANDED.
Also added a colored background to the catalog demo in order to see the corners of the sheet.

Does not include functionality or the modal side sheet. At the moment, the catalog demo includes a placeholder standard side sheet with a show/hide button that toggles the visibility between GONE and VISIBLE.
