Move c/b/webdata/code which does not depend on chrome/ to components/webdata/

Moving to components/webdata/autofill:

c/b/api/webdata/autofill_web_data.h
c/b/webdata/autofill_change.(cc|h)
c/b/webdata/autofill_entry.(cc|h)
c/b/webdata/autofill_table.(cc|h)
c/b/webdata/autofill_web_data_service.(cc|h)

moving to components/webdata/common:

c/b/api/webdata/web_data_service_base
c/b/api/webdata/web_data_service_consumer
c/b/api/webdata/web_data_results

c/b/webdata/web_data_request_manager
c/b/webdata/web_data_service_base
c/b/webdata/web_data_service_test_util
c/b/webdata/web_database
c/b/webdata/web_database_service
c/b/webdata/web_database_table
c/b/webdata/webdata_constants

No change in how Webdata is built (it is still part of chrome_browser).

All source files were moved using //tools/git/move_source_file.py,
which updates includes of moved files, sorts include order, and
updates header guards.

The only manual bits of this change were:
- Update .gypi files
- Update DEPS files
