Remove DNA_workspace_types

Accidentally committed after choosing not to rename

Fix search menu using wrong search list in full window draw mode

Turns out we can't use static struct data here, so just adding logic for
freeing custom search data when needed.

Remove redundant TODO mark

workspaces.blend file contain nothing but workspaces (mostly), so there's
nothing to skip when reading.

Don't append temporary screen-layouts with workspaces

Bundle default workspace user configuration file with Blender

This contains nothing but the old screen-layouts converted into
workspaces (and "Default" layout/workspace is now called "General").

Note that this adds the workspaces.blend directly, no datatoc conversion
is used like for default startup.blend. Mainly for these two reasons:
* Appending only supports regular .blend files
* Regular .blend is much smaller than datatoc one (181kB vs. 1.4MB)

Rename workflow.blend -> workspaces.blend

Idea was that workflow.blend could be used for non-workspace data later,
but it's not worth the confusion it may cause.
