Add a new feature named 'perf-tui'. Adding this into the
PERF_FEATURES variable in perf.inc will enable the perf TUI (Text-base
UI) user interface on a target, which adds libnewt and turns on the
perf text UI options in perf, if perf is included in an image.
If 'perf-tui' isn't named as a feature (the default), the perf TUI
will be disabled and unavailable.
