perf ui browser: Add ->rows to disambiguate from ->height
The ui_browser->height is about the whole browser "window", including
any header, status lines or any other space needed for some "Yes", "No",
etc buttons a descendent browser, like hist_browser, may have.
Since the navigation is done mostly on the ui_browser methods, it needs
to know how many rows are on the screen, while details about what other
components are, say, if a header (that may be composed of multiple
lines, etc) is present.
Besides this we'll need to add a ui_browser->refresh_dimensions() hook
so that browsers like hist_browser can update ->rows in response to
screen resizes, this will come in a follow up patch.
This patch just adds ->rows and updates it when updating ->height, keeps
using ->height for the only other widget that can come with ui_browser,
the scrollbar, that goes on using all the height on the rightmost column
in the screen, using ->rows for the keyboard navigation needs.
