Fix coding style issues flagged by nxstyle in files touched by the
SO_TIMESTAMPING series. These are pre-existing issues, not introduced
by the SO_TIMESTAMPING patches:
- inet_sockif.c: missing blank lines after declarations
- ipv4_input.c: missing blank line after declaration, bad comment alignment
- can_input.c: bad indentation inside #ifdef block
- getsockopt.c: bad comment block alignment, bad brace alignment
- setsockopt.c: wrong column position of comment
- sim_netdriver.c: missing blank lines after declarations

Replace compile-time CONFIG_ARCH_HAVE_NETDEV_TIMESTAMP with
a runtime NETDEV_RX_STAMP bit in net_driver_s.d_features.
Drivers providing hardware RX timestamps set the flag at
probe time; the stack checks it at runtime.

Move RX timestamp storage from net_driver_s.d_rxtime into
iob_s.io_time so each IOB carries its own timestamp through
the stack. Remove old iob_trycopyin/iob_copyout timestamp
packing in CAN/PKT/UDP paths. Fix iob_clone_partial to copy
io_time before source pointer advances to NULL.

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.

To avoid memory waste, can add support for using an independent iob buffer
The IP protocol often configures CONFIG_IOB_BUFSIZE to be relatively large,
such as 512, for higher throughput. However, the buffer required by CAN is
fixed at a length of 16 or 64. If the system's IOB is directly used,
a lot of memory will be wasted.

Add support for network statistics for CAN.
It includes counters for receive, sent
and drop frames.

detail: Add g_ prefix to can_dlc_to_len and len_to_can_dlc to
follow NuttX coding style conventions for global symbols,
improving code readability and maintainability.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Because CAN is a broadcast protocol, each conn needs to be given independent data to avoid mutual interference.
