When an application call the library in a system without amdgpu,
it may always print out "rsmi_init() failed". Suppress the error
message in the library.

The (temperature == nullptr) check happens only when HBM temperature is retrieved.
This check needs to apply in other cases as well, hence moving this outside the HBM condition.
This should return RSMI_STATUS_INVALID_ARGS consistently in all cases when nullptr is passed through rsmitst.

Previously, RSMI assumed that the event counter values returned
from perf were only new events. But in fact, when we read the
counter values, they are running totals. To account for this, we
now record the value we read and take the difference between the
current value and the previously recorded value.

Previously, during the rsmi_init discovery process, the existence
of an hwmon# directory was used to distinguish between gpus nodes
and non-gpu nodes. This isn't reliable in some scenarios. Instead,
the existence of the vbios_version file is used as an
indicator that the node is indeed a gpu.

If we fail to find an expected temperature or voltage label
file, previously we were attempting to re-add a mapping of file
index to sensor types. Attempting to insert a map item that is already
present has no effect, so there should be no functional change.
This was a remnant of old code that should have been deleted.

The environment variable RSMI_DEBUG_INFINITE_LOOP is introduced
to facilitate debugging RSMI in user applications. When this
env. variable is non-zero, an infinite loop will be entered in
rsmi_init(). At this point, a debugger can be attached and RSMI
can be debugger. This only applies to debug builds.

Previously, when a process holding a shared mutex was killed,
the next time an RSMI application was started, it would not be
able to obtain the mutex--the application would have to exit.
This fix uses pthread_mutexattr_setrobust() to detect this
situation and act accordingingly.
Also, add some missing, needed mutexes and move mutexes
closer to where the protect resource is used.

A special mode of operation to achieve minimal performance variation by letting
the user have the ability to provide the desired frequency to be set as the soft limit.
The user can control the entry and exit to the mode via rocm-smi a mechanism to
enter / exit performance determinism mode as below.
Enter performance determinism mode:
- hold a lock
- write performance_determinism to power_dpm_force_performance_level
- write input clk_freq to pp_dpm_sclk
- release lock
Exit performance determinism_mode:
- hold a lock
- write auto to power_dpm_force_performance_level
- release lock

Event bitmask in KFD SMI event is now replaced with event index in
the SMI event message. Sending a event bitmask, which was a 64-bit
field with only 1 bit set, was quite wasteful of memory and also
potentially limiting to 64 events. Instead the kernel would send
event index in the SMI event message. As a result, update the
KFD SMI event handling to expect the event index in the message.
