metagn 1660ddf98a make var/pointer types not match if base type has to be converted (#24130 )

split again from #24038, fixes
https://github.com/status-im/nimbus-eth2/pull/6554#issuecomment-2354977102

`var`/pointer types are no longer implicitly convertible to each other
if their element types either:

* require an int conversion or another conversion operation as long as
it's not to `openarray`,
* are subtypes with pointer indirection,

Previously any conversion below a subrange match would match if the
element type wasn't a pointer type, then it would error later in
`analyseIfAddressTaken`.

Different from #24038 in that the preview define that made subrange
matches also fail to match is removed for a simpler diff so that it can
be backported.
