touch/focaltech: Compressed MS and add SS_WATER.
Change list:
1. Compress the mutual-sensing data.
The purpose is to reduce the data count of heatmap through SPI.
To compress the mutual-sensing data in firmware side, and to
decompress it in kernel driver side.
It reduces the transferring data form 1088 bytes to 50 bytes/per finger).
2. Add water-on self-sensing data.
Bug: 228953908
Test: Touch, v4l, twoshay works well.
