Add MaterialTextView binding

[colemancda]

Overview

Adds a binding for com.google.android.material.textview.MaterialTextView to the AndroidMaterial module, alongside the existing MaterialButton and MaterialDivider bindings.

• Sources/AndroidMaterial/swift-java.config: registers the class with the wrapper generator.
• Sources/AndroidMaterial/MaterialTextView.swift: the binding — the four standard widget constructors plus the class's declared setTextAppearance(_:_:) and setLineHeight(_:) overrides, extending TextView (consistent with MaterialButton extending Button).

Motivation

Enables Material 3 text rendering for view-based consumers; in particular, AndroidSwiftUI's Text can render with MaterialTextView once this is available, completing its Material Components migration alongside MaterialButton and MaterialDivider.

Testing

• Package builds on the host toolchain.
• Verified at runtime on an emulator (API 36, arm64) with Material Components 1.14.0 under a Theme.Material3.DayNight theme: instances construct via JNI and render text correctly.
