[Internal] Kill our custom baseline textview

[SUPERCILEX]

This went through: material-components/material-components-android#56

Should be done when we upgrade to support lib v28 after v4.2.1.

Here's the class: https://github.com/firebase/FirebaseUI-Android/blob/8bda799672d44fd2994d2498441859fae3ccb530/auth/src/main/java/com/firebase/ui/auth/util/ui/BaselineTextInputLayout.java

@SUPERCILEX you're everywhere! SGTM

[samtstern]

Upgrading to compile SDK 28 gave me some weird build issues, so will deal with this in 4.3.0 (which will come soon after 4.2.1).

[samtstern]

This has been released in version 4.3.0.

Looking at TextInputLayout.class in the 28.0.0 release of the design support library, I don't think your change made it in :-/

[SUPERCILEX]

Huh, I guess it's only available in AndroidX. Maybe it's time to do the migration?

[samtstern]

Yeah one of many reasons! I guess we have to just swallow that pill soon.
