* @ExperimentalForeignApi for all declarations that operate on
unmanaged memory (i.e. pointers and references)
* @BetaInteropApi for the rest of the interoperability declarations,
namely Swift/CInterop-specific interfaces and convenience-functions
### Implementation details
* Some typealiases are not marked explicitly because it crashes the compiler,
yet their experimentality is properly propagated
* License header is adjusted where it previously had been existing
* Deprecated with ERROR interop declarations that are deprecated for more than
two years are removed
* WASM target interop declarations are deprecated
* Deliberately make Boolean.toByte and Byte.toBoolean foreign-experimental to scare
people away
