Hardware: Added Processor Cache Memory Provider

New Providers:
    * LMI_ProcessorCacheMemoryProvider
    * LMI_AssociatedProcessorCacheMemoryProvider

Other Changes:
    * Optimized usage of string constats
    * Fixed wrong usage of pointers in dmidecode.c
    * Filled unknown mandatory fields in providers with "Unknown" value
    * Replaced hard coded numbers with LMI constants
    * Minor optimization - don't gather data which won't be used
