lib: rename internal module declaration as internal bindings

This is a follow-up to #45551 .

Renaming NODE_MODULE_CONTEXT_AWARE_INTERNAL
to NODE_BINDING_CONTEXT_AWARE_INTERNAL.
As these bindings are already loaded with the function internalBinding
in the JS land, the term "internal binding" can be straightforward to
be adopted.
