image.bbclass: rename COMPRESS(ION) to CONVERSION

With the enhanced functionality, the term "compression" is no longer
accurate, because the mechanism also gets used for conversion
operations that do not actually compress data.

It is possible to remove this naming problem in a backward-compatible
manner by including COMPRESSIONTYPES in CONVERSIONTYPES and checking for
the old COMPRESS_CMD/DEPENDS as fallbacks.
