JVM IR: disable SAM conversion in case type has 'in' projection

... and the corresponding type parameter has a non-trivial (i.e.
non-`Any?`) upper bound.

The best solution here would be to get rid of
`removeExternalProjections` completely, and just use the type of the
argument at the call site, but see KT-52428.
