Allocate required device and host buffers to be able to interact with
the 2nd level trap handler.

[ROCm/ROCR-Runtime commit: 8d666dea01]
Code is valid for gfx9 GPUs excluding gfx94x.
1st level trap handler will use TTMP13[22] to indicate host trap and
TTMP13[21] to indicate stochastic trap.
For each PC sampling method (hosttrap and stochastic), we use a double
buffering mechanism to transfer data between GPU and host.
The GPU will dump data into one buffer while CPU may be reading data
from the other buffer. There are 2 separate signals, one for each
buffer.
When signal != 0, the buffer belongs to the GPU and the GPU can write
to it. Once the buffer has reached the high watermark, the GPU will
set the signal to 0 to wake up the host and so that the host can try
to switch the buffers and read the data.

[ROCm/ROCR-Runtime commit: 431a70471e]
Create dedicated CP queue with highest priority for PC Sampling. Reduce
the highest priority that LRT's can set for existing API so that PC
Sampling queue will always have highest priority over any other CP
queues

Add new PC Sampling API to list the supported PC Sampling methods and
options on a specific agent. If there is already a PC Sampling session
active on this agent, the list of methods returned will be reduced to
methods that can be run simultaneously with the current active session.

There are several ways to ignore the formatting commit:
1. Configure local project:
git config --local blame.ignoreRevsFile .git-blame-ignore-revs
2. Run blame with an argument:
--ignore-revs-file .git-blame-ignore-revs
example:
git blame --ignore-revs-file .git-blame-ignore-revs rdci/src/rdci.cc
