Add Android files / remove prebuilts

Add the license files needed by Android, add Android build rules
and remove prebuilts.

The build rules include test targets. One of the tests fails already so
it is "suppressed" here.

Bug: 152746105
Test: atest --host s2-geometry-library-java-tests
Test: atest S2GeometryLibraryJavaTests
Change-Id: Iaa7033e866a7897dd6ced01ac72b3df051a9975f
