Adds the concept of a scalebar display "prefix" so that the synteny display can show the assembly name in each row
The prefix is "combined with the refname" if a leftmost block is a content block, or otherwise just put at position absolute leftPx:0
with a show all regions the leftmost block is a padding block, so you can see the assemblyname gets detached from the chromosome names
this approach is similar but a little different from the approach mentioned here https://github.com/GMOD/jbrowse-components/issues/3414 which had a always floating leftmost paper, but this would cover up the leftmost refname
It is also a little different from pairing discussion with garrett who proposed adding it to minicontrols (on right side of screen). it just felt a bit off :)
