Move rpmsg internal APIs from public header include/nuttx/rpmsg/rpmsg.h
to private header drivers/rpmsg/rpmsg.h. These APIs are only used within
the rpmsg driver implementation and should not be exposed to external
modules.
Moved APIs:
- rpmsg_modify_signals()
- rpmsg_ns_bind() / rpmsg_ns_unbind()
- rpmsg_device_created() / rpmsg_device_destory()
- rpmsg_register() / rpmsg_unregister()

Add a new getrecvbuf callback to the SPI slave device operations
that allows the slave device to provide a pre-allocated receive
buffer directly to the controller. This enables zero-copy data
transfer by allowing the controller to receive data directly into
the device's buffer instead of copying.
Changes:
- Add SPIS_DEV_GETRECVBUF macro and getrecvbuf callback to
spi_slave_devops_s structure in include/nuttx/spi/slave.h
- Implement getrecvbuf in rpmsg_port_spi_slave driver
- Update getdata to return 0 as it's no longer used for this path

The cmdhdr->len was uninitialized before being used in SPI exchange
operations. This caused incorrect transfer lengths.
Changes:
- Initialize cmdhdr->len to sizeof(struct rpmsg_port_header_s) during
initialization for both SPI master and slave drivers
- Use port.txq.len instead of cmdhdr->len for TX exchange length
- Use port.rxq.len instead of cmdhdr->len for RX getdata length

This commit fixes a memory alignment issue in the rpmsg subsystem.
The previous implementation used a flexible array member (rdev[0])
in struct rpmsg_s, but due to automatic 8-byte padding, rpmsg->rdev
could differ from the transport layer's rdev address (e.g.,
rpmsg_virtio->rvdev.rdev), causing potential memory corruption.
Changes:
- Remove rdev[0] flexible array member from struct rpmsg_s
- Add rpmsg_get_rdev_by_rpmsg() inline helper to calculate rdev
address as (rpmsg + 1), ensuring correct pointer arithmetic
- Update all rpmsg->rdev references to use the new helper function
- Fix rpmsg_virtio_notify_wait() to use correct container_of macro

Use rpmsg_send_offchannel_raw to fix stuck issue avoid getting stuck
when remote destroy ept.
When send messages from ap to android in Rptun thread, Android may
have sent NS_DESTROY through rpmsg_port and changed ept->dst to
RPMSG_ADDR_ANY in rpmsg_port_ns_callback; So rptun thread may be
stuck at this time because rpmsg_send detected dst_ept's dst_addr
is RPMSG_ADDR_ANY.
