[8u] RFR 8217731: Font rendering and glyph spacing changed from jdk-8 to jdk-11

[Alvarez, David]

Hi,

I would like to request a review and jdk8u-fix-yes for this backport related
to the interpreter mode to use in Freetype.

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8217731
  https://hg.openjdk.java.net/jdk/jdk/rev/18629738b64b

The problem happens when using newer versions of Freetype.

Webrev:
  http://cr.openjdk.java.net/~alvdavi/webrevs/8217731/webrev.8u.00/

It is an almost clean backport, only the imports and file name had been 
changed.

I'm sending this for jdk11u too.
