Marks experimental JS export annotations.
Note that behavior of these annotations will likely be changed in the future.
Usages of such annotations will be reported as warnings unless an explicit opt-in with
the OptIn annotation, e.g. @OptIn(ExperimentalJsExport::class)
,
or with the -opt-in=kotlin.js.ExperimentalJsExport
compiler option is given.
