perf util: Move block TUI function to ui browsers
It would be nice if we could jump to the assembler/source view (like the
normal perf report) from total cycles view.
This patch moves the block_hists_tui_browse from block-info.c to
ui/browsers/hists.c in order to reuse some browser codes (i.e
do_annotate) for implementing new annotation view.
v2:
---
Fix the 'make NO_SLANG=1' error. (Change 'int block_hists_tui_browse()'
to 'static inline int block_hists_tui_browse()')
