blender: new port

[jasonliu--]

Description

Blender is a 3D computer graphics creation suite.

Some notes to whichever committer(s) reviews this PR:

• I realize that this version (2.82a) is already not the newest version of Blender. However, when I started work on packaging Blender and all of its dependencies at the beginning of the pandemic, 2.82a was current. I've already started work on the portfile for the current version of Blender, but I would like to get 2.82a into the ports tree first.
• I have intentionally left off openmaintainer from the list of maintainers for the time being. My plan is to add openmaintainer to the list when I submit a PR for the latest up-to-date version of Blender.
• Blender is fairly large; I wouldn't be surprised if some or even all of the Travis builds time-out.

Type(s)

• bugfix
• enhancement
• security fix

Tested on

macOS 10.11.6 15G22010

complex port, indeed. Great showcase for your compat defines! Builds throgh on all the CI bots. LGTM!

Well, Jason, I think let's go with it, and see how it fares in the wild.

Great, thanks Ken! I've already started working on the portfile for the newer version that has been released, so this PR is definitely only just the beginning for this port. :)
