debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Currently the mdio communication is part of the monolithic 'full netdevs'.
This commit serves as an way to add modularity for the netdevs drivers.
A new upperhalf/lowerhalf mdio device comes with this commit that manages the data transfer ofer mdio interface.
