perf report: Support a new key to reload the browser
Sometimes we may need to reload the browser to update the output since
some options are changed.
This patch creates a new key K_RELOAD. Once the __cmd_report() returns
K_RELOAD, it would repeat the whole process, such as, read samples from
data file, sort the data and display in the browser.
v5:
---
1. Fix the 'make NO_SLANG=1' error. Define K_RELOAD in util/hist.h.
2. Skip setup_sorting() in repeat path if last key is K_RELOAD.
v4:
---
Need to quit in perf_evsel_menu__run if key is K_RELOAD.
