Autogenerate source files with current version and check it during Main dispatcher initialization

[qwwdfsad]

Feedback shows that from time to time users accidentally update kotlinx-coroutines-core version, but not kotlinx-coroutines-android version. Such inconsistency can lead to various incompatibilities and runtime errors related to implementation details.

We can automatically autodetect such situations and report an error (NB: it should have a switch to disable it) if kotlinx-coroutines-core and kotlinx-coroutines-android have a different version.

Note that the classic solution "put library version in META-INF or resources" does not work because it can cause ANR due to file read (see #878)
