Subject: AAPT2: Add version collapsing

When an app specifies (or imports) resources with various
configurations for different SDK versions, specifying
a minSdk will make many of those resources unreachable.

Version collapsing will prune out the resources specified
for SDK versions less than the minSdk.

If, however, there is no exact matching resource for the
minSdk version, the next smallest SDK version is kept.
