Add extended core mask for up to 256 cores.

[Dimi1010]

Summary

Adds infrastructure for extended core mask that allows addressing up to 256 machine cores.
Part of #1717

Proposal

Current server grade processors frequently exceed 32 cores. The current core mask implementation cannot address these cores as it is limited to 32 bits. The PR proposes adding a new mask object LongCoreMask that is based on std::bitmask instead of uint32_t that can accommodate up to 256 machine cores. The maximum of 256 was chosen as it is the highest available count that would not require changing SystemCore::CoreId data type from uint8_t to uint16_t. Further expansion can happen in a future PR.

Changes

• Added LongCoreMask to support larger machine core count.
• The field SystemCore::Mask has been deprecated to disambiguate between the short and long core masks. The field would also be unsafe for system cores with IDs over 32, as they can't be represented. It has been replaced by SystemCore::getShortCoreMask() which dynamically computes the mask from the current SystemCore::CoreId.
• Added an overload to createCoreVectorFromCoreMask which uses return value instead of out parameter.
• Added validation for functions createCoreMaskFromCoreVector and createCoreMaskFromCoreIds. They will now throw std::out_of_range exception if they encounter CoreId >= 32.
• Fixed documentation comments. Comments without @brief did not have their documentation added as short documentation.

Not planned in this PR

• Add support for LongCoreMask in PfRingDevice.
• Add support for LongCoreMask in DpdkDevice.
