[master] API and boot image updates to import RI BigInteger

This reorders methods, omits a redundant "implements" spec, and adds
<x>ValueExact() methods, which are in OpenJDK 8, but hadn't been
implemented on Android.

Also update the boot image profile to compile BigInteger-required
methods that used to be native. Some of these must be compiled to
avoid ART test timeouts.
