IOT-2539 Clean unused code warnnings

credresource.c:
Removed the [-Wunused-const-variable=] warning
The CRED_EMPTY_ROOT_MAP_SIZE was used in the past but is no longer
referenced anywhere in the code.

provisioningclient.c:
Removed the [-Wunused-const-variable=] warning
The SUPPORTED_PRMS array was used in the past but is no longer
referenced anywhere in the code.

ocserver.cpp
Removed the [-Wunused-variable] warning
Looking at the logs a instance that gDeviceUUID was used could not
be found at any point in time.

stacktest.cpp:
Removed the [-Wunused-variable] warnings
Variables peer, pinNumber, and pmSel were only used in Direct Pairing
related unit tests which were removed as part of IOT-2306.

provisioningclient.cpp:
Removed the [-Wunused-function] warning
The InputPdACL function was only used by the Direct Pairing code
that was removed as part of IOT-2306.
