[DOM Distiller] Compress resources to save 86 kB on Android.

This CL compresses DOM distiller's resources, which reduces Chrome's
binary size by 86 kB on Android. Details:
* Add compress="gzip" to all dom_distiller_resoruces.grdp items.
* Add resource_utils.* with GetResrouceFromIdAsString() to centralize
  ui::ResourceBundle() usage, and perform uncompression.
* Ensure that all IDR_* usage go through GetResourceFromIdAsString().
  * Exception: WebUI (for chrome://dom-distiller), which uses
    content::WebUIDataSource, so decompression is already handled.

Also update third_party/zlib:
* Add GzipUncompress(base::StringPiece, std::string*), which
  allocates the output string (used by GetResrouceFromIdAsString()).
* Add CompressionUtilsTest::GzipUncompressionFromStringPieceToString.
