ALSA: seq: Add ioctls for client UMP info query and setup

Add new ioctls for sequencer clients to query and set the UMP endpoint
and block information.

As a sequencer client corresponds to a UMP Endpoint, one UMP Endpoint
information can be assigned at most to a single sequencer client while
multiple UMP block infos can be assigned by passing the type with the
offset of block id (i.e. type = block_id + 1).

For the kernel client, only SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO is
allowed.
