[FIR2IR] Fix cast insertion for SAM conversion

Browse Source 
The rule is: no cast is required iff the argument type is a
non-reflection function type and a subtype of the expected
function type.
We approximate the cone types using the FIR2IR specific config
to account for intersection types, captured types, etc.
