Prevent field_size from being specified on keyword fields.

Currently, there are a few keyword fields that also specify field_size.
This is misleading, because the size for keyword fields are
automatically calculated from the number of keywords, so field_size is
ignored.

This patch removes any references to field_size in keyword fields. It
also adds an assert in make_computed_style_base to prevent this from
happening in the future.

This patch does not change generated code.
