perf tools: Add support for parsing PERF_SAMPLE_READ sample type
Adding support to parse out the PERF_SAMPLE_READ sample bits. The code
contains both single and group format specification.
This code parse out and prepare PERF_SAMPLE_READ data into the
perf_sample struct. It will be used for group leader sampling feature
comming in shortly.
