The OnChangedListener provides a callback that MaterialShapeDrawables can use to invalidate themselves when the associated ShapeAppearanceModel changes. This allows for modifying the ShapeAppearanceModel through the get/setShapeAppearance methods that the Shapeable interface exposes without having to update the client to redraw itself.

Prior to this change, when setLayoutDirection is called on a parent/ancestor View of a Chip, the updated layout direction could be propagated to the Chip without updating its text padding. This change forces a padding update whenever layout direction changes.

Created TextAppearanceFontCallback (a fork of FontCallback) in order to pass parameter indicating whether font was resolved synchronously.

Avoid setting custom ExploreByTouchHelper as delegate in pre-N unless there's a close/trailing icon. This is necessary to workaround a Talkback bug.

The previous code was setting total padding (both start & end) as just end padding of the parent TextView and relying on the invalidation phase drawing the text in the correct place by shifting canvas with computed offset of start padding. This is risky as Chip may be just re-laid without actually invalidating it and render wrong paddings. Also RTL layout direction is incorrectly identified as LTR during layout sometimes, which makes the text being rendered with incorrect offset.
This change sets the paddings correctly removing the need of manual offsetting during onDraw() and relies purely on TextView for its text rendering.

This is in preparation of larger change of moving CollapsingTextHelper onto TextAppearance to fix related bugs & avoid code duplication.
1. Introduces a version of getFontAsync() in TextAppearance that doesn't require TextPaint as an argument.
2. Refactors the existing getFontAsync to wrap the new implementation.
3. Fixes a bug - TextAppearance would not apply the correct typeface from a style when fontFamily was not present in the style def.

Remove overridden getText method, and rely on the TextView's implementation.
This also fixes accessibility issues when Talkback granularity is set to "word" or "characters".

1) It's no longer necessary because Chip extends AppCompatCheckbox and TextView sets this if it's not explicitly set by the user
2) This prevents developers from indicating that a chip should not be exposed to accessibility.

This is preventing completions of attribute names for Chip and the attribute panels shows up empty for Chip.
Rename R.styleable.ChipDrawable to R.styleable.Chip and update ChipDrawable to use it.
AS 3.2 canary > 14 (currently 16) is required to see the attributes in the attribute panel.
