Since its constructor can now be used publicly. Copy input mappings and check the type of input indexes.

rollback/update Dataset and DataArray constructors
Drop the `indexes` argument or keep it as private API. When a `Coordinates` object is passed as `coords` argument, extract both coordinate variables and indexes and add them to the new Dataset or DataArray.

skip create default indexes...
... When a Coordinates object is given to the Dataset constructor

invariant checks: maybe skip IndexVariable checks
... when check_default_indexes is False.

fix tests: prevent index conflicts
Do not extract multi-coordinate indexes from DataArray if they are overwritten or dropped (dimension coordinate).

re-add coord indexes in merge (dataset constructor)
This re-enables the optimization in deep_align that skips alignment for any alignable (DataArray) in a dict that matches an index key.
-
create coords with default idx: try a cleaner impl
Coordinate variables and indexes extracted from DataArrays should be merged more properly.

allow skip align for object(s) in merge_core
This fixes the decrease in performance observed in Dataset creation benchmarks. When creating a new Dataset, the variables and indexes in `Coordinates` should already be aligned together so it doesn't need to go through the complex alignment logic once again. `Coordinates` indexes are still used to align data variables.

fix Coordinates._overwrite_indexes callback
mypy was rightfully complaining. This callback is called from Aligner only, which passes the first two arguments and ignores the rest.

fix Self undefined error with python < 3.11
Pyright displays an info message "Self is not valid in this context" but most important this should avoid runtime errors with python < 3.11.
