Selectively display sections in right panel

[tcwan]

Is your feature request related to a problem? Please describe.
I am trying to use gdbgui for debugging bare-metal ARM code running in QEMU.

There are a lot of display sections in gdbgui right panel which do not make sense in this use case.
I am especially interested in the register panel contents, which gets pushed out of view each time.

Describe the solution you'd like
I would like to be able to control which sections are enabled and displayed, as well as the ability to rearrange the sections.

Describe alternatives you've considered
Make the right panel occupy the entire height of the window to provide more space.

Additional context
I'm running on macOS Mojave, with multiarch gdb 9.1 and qemu 4.2.0 installed using MacPorts.

You should be able to collapse sections you are not interested in by clicking the blue rows
