Implement default GPU power cap functionality in rsmitst.
It is available in the "rsmitstReadOnly.TestPowerRead" test, and
is displayed as: "Default Power Cap: #uW" (where uW is microwatts).

For device-getter functions, allow users to specify a nullptr
for the provided buffer. In those cases, the function will return
RSMI_STATUS_NOT_SUPPORTED if the hardware or system software does
not support the function. If the function is supported, then
RSMI_STATUS_INVALID_ARGS will be returned, unless a different
error is encountered.
Additionally, tests and documentation were updated to reflect
this change.
