Implement Xz compressor functions.

The new XzCompress() function is similar to BzipCompress() function but
uses the Xz compression algorithm.

This patch simplifies the unittests of the compressors and reuses the
client-side decompresor implementation instead of repeating the
implementation in the delta generator. This patch removes the unused
compression/decompression functions.

Bug: 24578399
TEST=Added unittests.
