the dependency on the coroutines library caused various problems like
KT-30778, or stdlib/runtime version conflicts.
The only function used was `runBlocking`, so this change replaces it
with the internal implementation based on the similar internal thing
from the stdlib.
#KT-30778 fixed
it conflicts with the compilation on daemon, so transistion should
be planned accordingly, and now it is not a good time for it.
The most important part of the renaming remains intact.
Partially reverts commit "Rename scripting libs and plugin - invert embeddable suffix"
now regular, unshaded libs, are named with suffix `-unshaded`, while
former `-embeddable` ones named without any suffix. This will encoursge
use of the shaded libs by default, avoiding conflicts with 3-party
libs packed into the `kotlin-compiler`.
Note, that only the "frontline" libs are renamed to avoid switching
problems, the ones that not normally used directly are left as is,
including the `kotlin-compiler` itself.
