[BuildRules] Added support to skip header consistency checks for selected files

[smuzaffar]

See cms-sw/cmssw#39710
Some times we need to keep the headers in the release to properly print the error and suggest a proper solution to developers. With this new build rule now one should be able to add <flags IGNORE_HEADER_CHECK="file1 file2"/> (where file1 and file2 are relative file path inder package's interface directory) to instruct scram to not run header consistency checks for these files.
