[CollapsingToolbarLayout] no functionality for setting fontFeatureSettings in setExpandedTitleTextAppearance(),setCollapsedTitleTextAppearance()

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
I have using a material prominent toolbar with CollapsingToolbarLayout(https://material.io/components/app-bars-top#anatomy) in my project.

I am using this font at the moment and I need to set a fontFeatureSetting for this collapsingToolbar title when collapsed/expanded.
However, it doesn't seem like there is a functionality for that provided until now. All I can see that is available are
`textColorHint; textColorLink; shadowColor; fontFamily; textStyle; typeface; textAllCaps; shadowDx; shadowDy; shadowRadius; hasLetterSpacing; textSize; `

**Describe the solution you'd like**

I would like to set fontFeatureSettings in a way that is for materialToolbar.
`@style/TextAppearance.Toolabar`
->
```

<item name="android:fontFeatureSettings">""</item>

```
so for, collapsingLayoutToolbar
`@style/TextAppearance.Toolabar`

or programatically (at the moment textAppearnce style with fontFeatureSetting is not doing anything at the moment with this)

`mToolbar.setCollapsedTitleTextAppearance(R.style.TextAppearance_Toolabar)`

**Additional context**
com.google.android.material:material:1.4.0 also tried 1.5.0 as well

Start at CollapsingToolbarLayout's setExpandedTitleTextAppearance and setCollapsedTitleTextAppearance entry points, then trace how the XML title text appearance is applied in expanded and collapsed states. Done means android:fontFeatureSettings works for both title appearances, including when configured through the programmatic setters.
