Add a 'mbed compile --debug' command

[janjongboom]

It's hard to figure out how to do a debug build using mbed CLI, instructions differ between mbed OS 2.0, 5.0/5.1, 5.2+... mbed CLI should have a command to make such a build.

FYI, here are the instructions:

• If using mbed 2.0, include -o debug-info in your workspace_tools/build.py and workspace_tools/make.py commands to build with debug symbols.
• If using mbed 5.1, add -o debug-info to your mbed compile command.
• If using mbed 5.2+, add --profile mbed-os/tools/profiles/debug.json to your mbed compile command.

I think as of 5.3, we simplified it a bit so you can just do --profile debug. Do you think this is enough?

@bridadan But that only works for 5.3... We should have a standard way of doing this across all versions of mbed OS.

What do you suggest? The way to go are profiles. This was a breaking change, and a replacement for old -o options that were not much clear what they do.

@0xc0170 Sure, but I think making debug builds is such a common action that we should add it to mbed CLI. Suggestion:

mbed build --debug

Which magically sets some stuff in mbed 2, builds with the right -o in mbed OS 5.2 and lower, and with the debug profile in mbed OS 5.3.

I see what you're saying @janjongboom, though there's a part of me that doesn't want to treat debug as "special" even though it is such a common operation.

@screamerbg do you have any thoughts on this?

[screamerbg]

I'll second @bridadan. @janjongboom I'll close the issue as there wasn't any activity for some time, but please reopen or create new with proposal how this could work as a workflow.

Isnt this just mbed compile --profile=deubg ?
