perf tools: Add support for displaying event parser debug info
Adding PARSER_DEBUG Makefile variable to enable building event scanner/
parser with debug enabled. This results in verbose output right out of
the scanner/parser.
It's useful for debuging the event parser. Keeping this only for event
parser so far.
