Add memory information to profiling.md

[FlexYourBrain]

Currently the profilers display Memory and LuaMem properties without any information on the unit type. This would be useful information to have in docs.

Info:
Both properties Memory and LuaMem are in kilobytes(kb) as we see here:

Memory - https://github.com/defold/defold/blob/dev/engine/profiler/src/profiler.cpp#L36

LuaMem - https://github.com/defold/defold/blob/dev/engine/lua/src/lua/lapi.c#L917-L921

Task:

• Add foot note for memory unit type information to the profiling.md

*NOTE This would be a good Hacktoberfest issue

Note: I updated the docs before you created the issue, but I had a typo in the docs so it was caught by the spellchecker and not published. Anyway, it's fixed now and the docs is updated.

I see a possible issue, the fix says Memory is the amount of memory in bytes used by the engine. - Isn't Memory in kilobytes? As Jcash shared here https://github.com/defold/defold/blob/dev/engine/profiler/src/profiler.cpp#L36.

Doh, indeed. Fixed just now.
