text-spacing: text-spacing-trim: Implement derived half-width font for
CoreText platform
https://bugs.webkit.org/show_bug.cgi?id=281340
rdar://137770955
Reviewed by Sammy Gill.
This is a preparation patch for text-spacing-trim.
According to specification, trimming should be done
by using OpenType "halt" feature.
This patch creates a derived half-width font by
enabling the OpenType "halt" feature of an existent font.
It also implements a way to verify if a given font
supports such feature.
