cmd/compile: don't inline fn with no shape params, but passed a shape arg
Don't inline a function fn that has no shape parameters, but is passed
at least one shape arg. This means we must be inlining a non-generic
function fn that was passed into a generic function, and can be called
with a shape arg because it matches an appropriate type parameter. But
fn may include an interface conversion (that may be applied to a shape
arg) that was not apparent when we first created the instantiation of
the generic function. We can't handle this if we actually do the
inlining, since we want to know all interface conversions immediately
after stenciling. So, we avoid inlining in this case.
Fixes #49309.
