[jfx11u] RFR: 8239589: JavaFX UI will not repaint after reconnecting via Remote Desktop

[Kevin Rushforth]

This is a mostly-clean backport to jfx11u. The only merge conflicts I had to fix were in `D3DPipeline.cc` to ignore two hunks from the patch, since the static library support is not present in 11 (this is the exact same thing I had to do for the FX 8u backport).

Tested on all three platforms, along with my other in-progress backports, all of which are aggregated in my [`kevinrushforth:test-kcr-11.0.12`](https://github.com/kevinrushforth/jfx11u/commits/test-kcr-11.0.12) branch.

Additional testing: verified on a remote desktop connection that disconnecting and reconnecting now works.
