Textarea isn't cloned properly in IE11

[m_gol]

IE11 fails the test checking for defaultValue to be cloned properly in textarea. This causes a test to fail, see:

cc @dmethvin, you said it's about splitting one support test AFAIK, do you have a fix ready?

[dmethvin]

Sorry, I don't, but I looked at it a while back. Seemed like IE11 fixed the cloning of checkboxes but not the cloning of textareas. We had both assumed by support.noCloneChecked and a single fixInput() for both. If we wanted to keep a single check we could reverse it and check a textarea, or take the hit and do two separate checks. We can do this in .1

I'm fine with reversing the check, it'll save size and will be simpler to implement.

Manipulation: Use textarea for missing IE defaultValue check

IE11 fixed the checkbox defaultValue issue but not textarea. Rather than creating a new detect name I'm reusing the old one to protect anyone who is unwisely using this externally. Re-fixing the defaultValue when it doesn't need to be done is not a problem, so leave that code for IE11.

Fixes #14716 Closes gh-1495
