Remove unused code from WebMimeRegistry.

Remove unused code from WebMimeRegistry.

WebCommon.h is never used in this header.

WebMimeRegistry::mimeTypeFromFile has no call sites (and I
can't find any in the last 4+ years).

jbroman@chromium.org changed reviewers:
+ jochen@chromium.org, mkwst@chromium.org

R=jochen for primary review
R=mkwst for content/common/mime_registry_messages.h IPC security review
