Update rendering library to be consistent with other vendors of OpenJDK

[Mekadrom]

After a brief conversation with others in the AdoptOpenJDK slack, I decided to open a ticket with an example of the differences between AdoptOpenJDK's chosen rendering native library and those of other OpenJDK vendors.

Note: Yes, the AdoptOpenJDK title bar size is now consistent with the default Windows title bar size. However, I don't believe that this is supposed to be the case. The windows pictured use the same exact code and that code extends JDialog.

The solution for this would be to implement the same or a similar native rendering library to the other vendors of OpenJDK.

If I need to add anything to this issue tracker, please let me know. I have no experience with this sort of thing and I actually have no clue what this whole native rendering library thing means, I'm just parroting martijnverburg from slack.

@Mekadrom what java version are you using? Is this a fonts issue or a rendering issue?

[Mekadrom]

@gdams This would be in 1.8u212b03, the change was noticed after upgrading from 1.8u181.

I prepared patches to backport the Marlin renderer 0.9.1.3 (like jdk14) to OpenJDK8 (jdk8u-dev).
See https://mail.openjdk.java.net/pipermail/jdk8u-dev/2019-November/010549.html

Enjoy FOSS Marlin renderer,

Needs discussing at @AdoptOpenJDK/tsc level

https://mail.openjdk.java.net/pipermail/jdk8u-dev/2020-May/011635.html shows the progress of the patch that @bourgesl is working on. We'll effectively wait for that to land upstream.
