py/objmodule: Add a table of built-in modules with delegation.
This replaces the previous QSTR_null entry in the globals dict which could
leak out to Python (e.g. via iteration of mod.__dict__) and could lead to
crashes.
It results in smaller code size at the expense of turning a lookup into a
loop, but the list it is looping over likely only contains one or two
elements.
To allow a module to register its custom attr function it can use the new
`MP_REGISTER_MODULE_DELEGATION` macro.
This work was funded through GitHub Sponsors.
