adb: implement LZ4 compression.
Add support for LZ4 compression, which compresses and decompresses far
more quickly than brotli, at the cost of worse compression ratio.
`adb sync -d system` speeds (in MB/s) on aosp_blueline-eng:
none brotli lz4
USB 3.0 120 110 190
USB 2.0 38 75 63
Bug: https://issuetracker.google.com/150827486
Test: python3 -m unittest test_device.FileOperationsTest{Uncompressed,Brotli,LZ4}
