1. Add SET_SESSION_FD cmd.
2. Support new delimit interface to send multi request in one ioctl.

rk3588 encoder needs buffer end address so zero size should be allowed.

The first jpegd vdpu2 will send codec info with normal register access
operation. But some old kernel will not support the codec info cmd 403.
Then kernel will discard the whole ioctl operation and let the first
decoding task failed.
So we separate codec info cmd from the normal register access cmd.

When /dev/mpp_service is opened and be forked to another thread the
leaked fd will increase file refcnt in kernel.
Then the codec kernel session will be leaked on mpp_destroy.

Batch mode will send multiple task to kernel at one time. And its
non-block poll is triggered by timer and looper.
This mode will reduce the ioctl overhead on ultra multi-instance case.
Main features and some notes:
1. Each client type has independence batch server.
2. Each mpp_device can attach or not attach to server independently.
3. When a device is attached to server all its tasks will be sent to
kernel through the server session not original client session.
4. The tasks are sent non-block and wait in block or non-block.
5. The batch mode can only be switch on/off when hardware is not
working.

NOTE: When MppDev is not output to mpp_dec the codec info update is
disabled.
This patch may cause kernel show the following log on old kernel:
mpp_process_request:1078: unknown mpp ioctl cmd 403
This log has no harm at all and new kernel will disable this log.

Tips: User should close fd before changing the client_type. Otherwise
the kernel will leak one info structure.

tips:
according to rcb_size descending, and sent rcb_info to the kernel.

1. Change mpp_device into a new layer for kernel drvier.
2. Separate mpp_service driver and vcodec_service driver.
3. Add mpp_service.c for /dev/mpp_service driver support.
4. Add global mpp_service info query interface.
5. Remove unused function in mpp_device.c
