Begin converting blink_skia_config from gyp to gypi.

Begin converting blink_skia_config from gyp to gypi.

According to the design document for the existence of the
blink_skia_config.gyp file, it was originally intended to be a gypi
as proposed in this change. However, at the time, use of the
'<(webkit_src_dir)' gyp variable was required to get the correct
location of WebKit. Since variables do not expand in 'includes' in gyp,
a gyp file was used instead so that it could be used in 'dependencies'.

These limitations no longer exist and converting to a gypi allows for
easier interoperation with gn. There will be a subsequent change to
Chromium to use this new file, and then the existing gyp file will be
removed in a follow-up change.
