The KFD only unmaps all queues, all dynamics queues or all process queues
since RUN_LIST is mapped with all KFD queues.
There's no need to provide a single type unmap so remove this option.

This turns previously global functions into static, thus removing
compile-time warnings such as:

Amdgpu driver uses 4-byte data type as DQM fence memory,
and transmits GPU address of fence memory to microcode
through query status PM4 message. However, query status
PM4 message definition and microcode processing are all
processed according to 8 bytes. Fence memory only allocates
4 bytes of memory, but microcode does write 8 bytes of memory,
so there is a memory corruption.
Changes since v1:
* Change dqm->fence_addr as a u64 pointer to fix this issue,
also fix up query_status and amdkfd_fence_wait_timeout function
uses 64 bit fence value to make them consistent.

Update PROCESS_QUANTUM, the time the hardware scheduler allows
processes to run before switching to other processes when it becomes
over-subscribed. Increase this to 10ms, to allow processes to better
amortize their task switch times.
Update HQD Quantum, the amount of time that an active queue stays
attached to the CP before we forcibly switch it for another active
queue for fairness.
Setting these so that HQD < PROCESS makes it easier to ensure that
we get fairness when we have multiple active queues on the device.
Otherwise we may start process-swapping before we get to all the
queues in a CP.

After the recent cleanup, the functionalities provided by the previous
kfd_kernel_queue_*.c are actually all packet manager related. So rename
them to reflect that.
