Make inspect work with avms by default and with go files if told so. In the
end this makes our CLI interface more consistent and usable. Drop useless
CompileAndInspect() compiler method along the way.

vm: copy slice in NEWARRAY/NEWSTRUCT
...
When performing NEWARRAY on a Struct or NEWSTRUCT on a Array,
underlying slice needs to be copied, because when it's capacity
doesn't matches it's length, underlying storage will be used
for appends even if it is already pointed at by another slice.

vm: introduce TryBool() for Element and use it in VerifyWitnesses
...
Script can return non-bool results that can still be converted to bool
according to the usual VM rules. Unfortunately Bool() panics if this
conversion fails which is OK for things done in vm.execute(), but certainly
not for VerifyWitnesses(), thus there is a need for TryBool() that will just
return an error in this case.
