bit_count should also work on imported type

[proppy]

Describe the bug

bit_count only seems to recognize on local types as valid argument.

To Reproduce

import float32;

const F32_SIZE = bit_count<float32::F32>();

produces the following error:

0005: const F32_SIZE = bit_count<float32::F32>();
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^--------------^ TypeInferenceError: The parametric argument for 'bit_count' should be a type and not a value.

aliasing the type locally w/:

type F32 = float32::F32;
const F32_SIZE = bit_count<float32::F32>();

workaround the issue.

Expected behavior

Imported type should also be recognized by the bit_count builtin.
