Allow RobotState::setFromIK to work with subframes (backport #3077)

[mergify]

Description

Fixes #3072

• Adds passing regression / sanity tests which verify that a RobotState can setFromIK with a collision object
• Adds failing tests demonstrating that RobotState cannot setFromIK with a subframe
• Fixes failing tests by modifying RobotState::setFromIK to consider subframes
• Adds some helper functions to the pilz tests for attaching objects / subframes and checking joint values

I tried adding the tests directly to the robot state tests, however, I was getting issues with no kinematic solver being associated with the planning group of the OneRobot fixture.

Pilz already had a test which was checking setFromIK, and appears to be setup with a kinematic solver, so I've added the tests there.

@rr-tom-noble sadly this one has conflicts too -- would you like to take a look? Thanks!

[sea-bass]

Seems to work!

Though @rr-tom-noble you said you were running into other issues? Is this just related to mixing source/binary installs but should be good pending that resolution?

[rr-tom-noble]

@sea-bass Given the tests, I'm confident that attaching objects & subframes through the RobotState now work with setFromIK.

Our in-practice use case a bit more complicated and involves using planning scene services to load and attach objects. It could be related to our mix of and binary and source, but my gut feel is that getFrameInfo() is working, and it's more related to the difference in how the objects are attached.

Given that issue arises from a somewhat different use-case, I think I'm happy with this PR as is, though I'm happy to leave it up to your discretion. I'll be looking into the next issue shortly.

@sea-bass I believe the failure is unrelated. I've seen it sporadically on a few other PRs
