Bluetooth: coredump: Expose header size and end marker to drivers
To separate the coredump header and data far more easily, give a
vendor driver the option to pad its header to a fixed size, by
moving the header size limit and ending marker to coredump.h:
- HCI_DEVCD_HDR_SIZE_MAX: the max header size
- HCI_DEVCD_HDR_END_MARKER: the header-ending marker
