Treat `Boolean.False` and `Boolean.True` as the corresponding primitives. Now, `Boolean.False == False` returns true.

# Important Notes
`False` and `True` constructs, that are converted to `ConstructorNode` during Truffle codegen, are handled specially in `ConstructorNode`. The easiest fix was to implement a similar special handling in `QualifiedAccessorNode`, although not the cleanest one.

A better solution would be to provide transformation of `Boolean.True` IR to a true literal in `ApplicationSaturation` compiler pass. But `ApplicationSaturation` pass does not handle `True`. Moreover, for our case, it is unnecessarily complicated.
