[kotlinp] Split :tools:kotlinp into "common" and "jvm" subprojects

The "common" subproject keeps only backend-neutral logic and depends
only on :kotlinx-metadata library. It takes the name of the former
project - :tools:kotlinp

The "jvm" subproject depends on the "common" one and also depends
on :kotlinx-metadata-jvm. It gets the new name - :tools:kotlinp-jvm

There is a lot of touched files in this commit. The majority of them
is just moved files (tests, test data, etc).
