Replace usages of GetRawDataResource in c/b/search/.

GetRawDataResource assumes that underlying files are not compressed,
whereas LoadDataResourceString automatically decompresses if necessary.

This is one of many CLs, in preparation of compressing all HTML, JS,
CSS, SVG files by default (meaning without requiring compress="gzip"
to be specified).
