perf report: Add support for PERF_SAMPLE_CODE_PAGE_SIZE
Add a new sort dimension "code_page_size" for common sort.
With this option applied, perf can sort and report by sample's code page
size.
For example:
# perf report --stdio --sort=comm,symbol,code_page_size
# To display the perf.data header info, please use
# --header/--header-only options.
#
#
# Total Lost Samples: 0
#
# Samples: 3K of event 'mem-loads:uP'
# Event count (approx.): 1470769
#
# Overhead Command Symbol Code Page Size IPC [IPC Coverage]
# ........ ....... ............................ .............. ....................

17.93% dtlb [.] Calibrate 4K - -
11.40% dtlb [.] __gettimeofday 4K - -
