[workload] add missing Microsoft.Maui.Controls.aar

[jonathanpeppers]

Description of Change

Fixes? https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1364884

The Microsoft.Maui.Controls.aar file is missing from the workload,
which includes the following Android resources:

res\anim\enterfromleft.xml
res\anim\enterfromright.xml
res\anim\exittoleft.xml
res\anim\exittoright.xml
res\values\strings.xml
res\layout\bottomtablayout.xml
res\layout\flyoutcontent.xml
res\layout\shellcontent.xml
res\layout\shellrootlayout.xml

I don't know what Android resources are needed and which package they
go in. We should actually do an audit and see if any are missing.

This seems like it was this way for the entirety of .NET MAUI Preview 6, and I guess no one noticed until now?
