perf report: Sort by sampled cycles percent per block for tui

Previous patch has implemented a new option "--total-cycles".  But only
stdio mode is supported.

This patch supports the tui mode and support '--percent-limit'.

For example,

 perf record -b ./div
 perf report --total-cycles --percent-limit 1

 # Samples: 2753248 of event 'cycles'

--------------------------------------------------

 v7:
 ---
 1. Since we have used use_browser in report__browse_block_hists
    to support stdio mode, now we also add supporting for tui.

 2. Move block tui browser code from ui/browsers/hists.c
    to block-info.c.

 v6:
 ---
 Create report__tui_browse_block_hists in block-info.c
 (codes are moved from builtin-report.c).

 v5:
 ---
 Fix a crash issue when running perf report without
 '--total-cycles'. The issue is because the internal flag
 is renamed from 'total_cycles' to 'total_cycles_mode' in
 previous patch but this patch still uses 'total_cycles'
 to check if the '--total-cycles' option is enabled, which
 causes the code to be inconsistent.

 v4:
 ---
 Since the block collection is moved out of printing in
 previous patch, this patch is updated accordingly for
 tui supporting.

 v3:
 ---
 Minor change since the function name is changed:
 block_total_cycles_percent -> block_info__total_cycles_percent
