Replace AppCompatRatingBar stars with vector drawables.

Binary size of minified obfuscated v7 demo:
 - before the change 2,401,715 bytes
 -  after the change 2,375,002 bytes
for the total reduction of about 26KB

Potential downsides:
 - additional overhead during the inflation, as we inflate the vector
   and then make a bitmap drawable out of it
 - slight variations in pixels along the edges (differences between
   the original PNGs and the new vector source) for golden images tests

Bug: 126209808
Bug: 126204182
Test: ./gradlew appcompat:appcompat:connectedCheck --info --daemon -Pandroid.testInstrumentationRunnerArguments.package=androidx.appcompat.widget
Test: ./gradlew textclassifier:textclassifier:assembleAndroidTest
Relnote: "AppCompatRatingBar PNG drawables have been replaced with vector sources.
This may cause slight changes in the visual appearance of individual stars."
