Implement a perf TUI using the python textual module. Using the
textual framework means that in most modern terminals the mouse is
supported, the color scheme can be configured, and screenshots made.

The work is dependent on the extensions to the perf python module
merged into perf-tools-next such as commit 88439191ad5e ("perf python:
Add callchain support"). It is also dependent on the python textual
module for TUI support.

v4: Fix typo of profle to profile and tweak argparse command
    description to only mention flamegraph after that support is added
    (Sashiko). Sashiko notes a high severity issue because the script
    depends on perf Python module extensions that are already
    merged. This is because Sashiko is testing the changes against the
    perf-tools rather than perf-tools-next. Verified
    rich.errors.MarkupError don't occur for kernel DSOs, primarily as
    there is always a space after the square brackets.

v3: Tweaks to commit messages (Sashiko).

v2: Migrate from inbuilt perf python interpreter to perf python
    module. Improve the flamegraph performance. Use the textual's
    color scheme rather than red and white.

Cool stuff, just tested it :-)

Thanks, applied to perf-tools-next, for v7.4.
