Is your feature request related to a problem? Please describe.
If you type /wa help into chat it'll print a bunch of commands related to WA, a few of them being profiling related (pstart/pstop/pprint). Nowadays these commands feel outdated after the profiling window was added and there isn't a chat command for opening the window.

Describe the solution you'd like
Add a /wa profiling-like command that opens up the profiling window, and possibly remove the old profiling commands.

Describe alternatives you've considered
The profiling window can currently be opened through the minimap icon or through keybinding, but neither of these are ideal for me as I keep 95% of minimap icons hidden and I don't like having to dedicate a keybind solely to WA profiling. So what I currently do is type /wa minimap -> right click minimap icon -> do my profiling -> /wa minimap. I could also type /run WeakAurasProfilingFrame:Show() but that's difficult to remember.

Additional context
WA version 5.17.1
