Merge 137535 - Fix incorrect forcing of text directionality in canvas_skia.cc.

Merge 137535 - Fix incorrect forcing of text directionality in canvas_skia.cc.

There were two issues:

1. RTL wrapping was simply not happening if your UI language locale was not RTL. Which made FORCE_RTL_DIRECTIONALITY not work.
2. RTL wrapping was not being applied in the SizeStringInt() path, which resulted in an inconsistency between the needed width for SizeStringInt() and DrawStringInt(), causing a problem with the label code resulting in truncation.

This CL fixes both issues.
