8272878: JEP 381 cleanup: Remove unused Solaris code in sun.font.TrueTypeGlyphMapper

[gredler]

During the recent JEP 381 removal of Solaris code, a few Solaris-specific constants and private methods were left behind in sun.font.TrueTypeGlyphMapper. This PR removes these unused odds and ends.

As per JEP 381, comments pointing to Solaris also need to be looked into or purged. There seem to be around 96 mention of Solaris still in java_desktop module...Can it be looked into in this PR?

[gredler]

I had initially wanted to keep this PR focused on a small, self-contained, fairly obvious change, since this is my first contribution to the project -- but I'm open to expanding the scope if I can get some direction.

It can be argued that many of the comments which mention Solaris still provide useful background information, e.g.:

jdk/src/java.desktop/share/classes/sun/font/CompositeFont.java

Line 243 in 739769c

* 2) Some font configuration files on Solaris reference two versions

jdk/src/java.desktop/share/classes/sun/font/StrikeCache.java

Line 81 in 90cd2fa

* suffice in Solaris UTF-8 locales where a single composite strike may be

jdk/src/java.desktop/share/classes/sun/font/TrueTypeFont.java

Line 744 in c36755d

/* This test is too stringent for Arial on Solaris (and perhaps

There are some other comments that could more obviously be fixed without issues:

jdk/src/java.desktop/share/classes/sun/font/FontManagerFactory.java

Line 42 in 6765f90

* A default implementation is given for Linux, Solaris and Windows.

@prsadhuk @prrace How would you like me to proceed?

[prrace]

I'm with Daniel on this one. I'd have to think about how to update those comments.
It isn't just an obvious case of "oh it mentions Solaris, I'll delete the whole thing".
So let's keep this PR focused.

[prsadhuk]

I do not have any objection to this looking into comments in future and not in this PR.
What about the code that has solaris in it?
https://github.com/openjdk/jdk/blob/master/src/java.desktop/unix/classes/sun/awt/X11/XScrollbarPeer.java#L37
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/native/liblcms/lcms2.h#L534 [it might need change in upstream though]

[gredler]

I think LittleCMS explicitly supports Solaris, so I doubt a patch removing Solaris support would be accepted upstream.

It does look like XScrollbarPeer should be cleaned up, but should it be done as part of this PR? Let me know either way.

I'm also looking for a sponsor for this PR, would either @prrace or @prsadhuk have some time to spare? Thanks!

[prrace]

Completely out of scope by a country mile to get anywhere near the LCMS support for Solaris.
In fact a really bad idea. Current JDK does not support Solaris but current LCMS may want to support older Solaris

I will sponsor this if it is ready. The submitter needs to type /integrate and only after that does /sponsor do anything.
