Introduce SinceKotlinInfo, load from serialized metadata

This is a way for future compilers to cause previous compilers to report
diagnostics on usages of some declarations. Diagnostic can have a message
(and/or error code), level (error, warning, or completely hide the declaration
from the resolution), and Kotlin version, since which the diagnostic should no
longer be reported
