Make upstream state indicator location more consistent with similar
state indicators (e.g. sparse). Group the short state indicator (`=`,
`<`, `>`, or `<>`) with other short state indicators immediately after
the branch name. Group the long state indicator (e.g. `u+2-1
origin/main`) with other long state indicators after the short state
indicators. Previously short and long upstream state indicators appeared
after all other state indicators.

Use a separator (`SP` or `GIT_PS1_STATESEPARATOR`) between branch name
and short upstream state indicator. Previously the short upstream state
indicator would sometimes appear directly adjacent to the branch name
(e.g. `(main=)`) instead of being separated (e.g. `(main =)`).
