Missing properties on Google.Android.Material.TextField.TextInputLayout

[jcmanke]

Xamarin.Android Version (eg: 6.0):

9.4.1.0

Operating System & Version (eg: Mac OSX 10.11):

Windows 10 Enterprise version 1903

Support Libraries Version (eg: 23.3.0):

Xamarin.Google.Android.Material 1.0.0-preview02

Describe your Issue:

android.support.design.widget.TextInputLayout does not fully implement the material text field spec, missing things such as the leading and trailing icons. com.google.android.material.textfield.TextInputLayout does, but it appears that the Xamarin.Google.Android.Material NuGet package simply maps the former control to the latter's namespace so methods such as setStartIconDrawable and setEndIconDrawable are missing.

Steps to Reproduce (with link to sample solution if possible):

Include any relevant Exception Stack traces, build logs, adb logs:
