Don't set metainfo ID for enhanced bookmarks extension

Don't set metainfo ID for enhanced bookmarks extension

The enhanced bookmarks extension is being updated to rely solely on
server-generated persistent IDs, eliminating the need to create IDs
in Chrome client code.

This is effectively a revert of 0f7d5081316ce979b96cc21f9143bf81372ac056
and 224e1d1867596f04e0e1fba030801c41c1b97727.
