remoteproc: core: Export the rproc coredump APIs

The remoteproc coredump APIs are currently only part of the internal
remoteproc header. This prevents the remoteproc platform drivers from
using these APIs when needed. This change moves the rproc_coredump()
and rproc_coredump_cleanup() APIs to the linux header and marks them
as exported symbols.
