Propagate max_sdk_version to manifest_fixer

If max_sdk_version is included in Android.bp that value will now be
propagated to manifest_fixer.py. This value will then be used to
override any maxSdkVersion attribute set on permission or
uses-permission tags in the android manifest if maxSdkVersion="-1".

Bug: 223902327
Test: add max_sdk_version to Android.bp for test app
Test: create permission in test app manifest with maxSdkVersion="-1"
Test: run test to check maxSdkVersion=max_sdk_version
