TextTextureRenderer: Fix word wrap behavior that regressed in 2.10.0

[frank-weindel]

Behavior has been reverted back to pre-2.10.0 behavior while retaining the zero-width space functionality.

• Moves textWrap() and measureText() methods to TextRendererUtils
  • Tests for both with the ability to mock up the C2D context version of measureText()
  • All direct context calls to measure text have been changed to use the util method.
  • The unit tests for textWrap() were originally written to pass for the original implementation prior to adding back the zero-width space functionality (plus a test for that)
• Removes splitWords()
• Moves tokenize() implementation for advanced renderer to TextRendererUtils w/ unit test

Todo

• Implement
• Unit tests
• Integration test

Fixes

• Regression with rendering text that uses normal spaces #488

[frank-weindel]

Test visually comparing 2.9 to this PR (2.10-new) showing that the original word wrap behavior is restored.

There is a difference when wordWrapWidth is set to 0, but this is due to #470 because the default maximum text texture width was changed from 2048 / 1 (Precision) = 2048 to 1920 (actual rendered pixel width of canvas). When the wordWrapWidth is set to 0, it automatically takes on the maximum texture width so that really long text will eventually break onto another line.
