Madvise uncompressed app images

We currently only madvise compressed app images, which accelerates
the immediate software decompression. However, uncompressed app images
also benefit from explicit madvise calls, as they are immediately
patched after mmap. This patching ends up dirtying most pages, and a
preceding madvise avoids excessive faulting during the fixup.

Bug: 336349058
Test: m + ART benchmark service w/ uncompressed app images
