[lib] Enhance Logger: gpu_metrics + enable console out

* Updates:
    - Env variable RSMI_LOGGING=0 or any other value
        -> all logging off
    - Env variable RSMI_LOGGING=1 -> logs only
    - Env variable RSMI_LOGGING=2 -> console only
    - Env variable RSMI_LOGGING=3 -> both logs + console
    - Metrics output includes hexdump of current file
      and decoded metrics (functions: logHexDump
      and log_gpu_metrics)
    - System info gathered, now includes if system's
      perceived endianness - little or big endian
      helpful for viewing decoded hexdump or any
      binary translation
    - Added templates for printing unsigned hex
      (print_unsigned_hex_and_int), unsigned integers
      (print_unsigned_int), and printing both unsigned
      hex and int with an optional header
      (print_unsigned_hex_and_int)
    - Fixed some build compile warnings/errors -
      ex. doing strncpys for sku or board names
      this operation is expected and needed
      and for temp file writes if unsuccessful
      we now properly send RSMI_STATUS_FILE_ERROR
    - Fixed on RHEL 8.8/9.x logrotate does not properly
      initialize
