Validate creating bind group layout with storage textures

Browse Source 
This patch adds the validation on the creation of the bind group
layout with read-only storage texture, write-only storage texture
and read-write storage texture. Currently read-write storage textures
are not supported in any shader stages.

This patch also fixes chromium:1061156.

BUG=chromium:1061156, dawn:267
