Implement fish completion (#29549)

* commands: provide more information to Command

* fish: Add script to generate fish completion

* fish: auto prepend `spack` command to avoid duplication

* fish: impove completion generation code readability

* commands: replace match-case with if-else

* fish: fix optspec variable name prefix

* fish: fix return value in get_optspecs

* fish: fix return value in get_optspecs

* format: split long line and trim trailing space

* bugfix: replace f-string with interpolation

* fish: compete more specs and some fixes

* fish: complete hash spec starts with /

* fish: improve compatibility

* style: trim trailing whitespace

* commands: add fish to update args and update tests

* commands: add fish completion file

* style: merge imports

* fish: source completion in setup-env

* fish: caret only completes dependencies

* fish: make sure we always get same order of output

* fish: spack activate
only show installed packages that have extensions

* fish: update completion file

* fish: make dict keys sorted

* Blacken code

* Fix bad merge

* Undo style changes to setup-env.fish

* Fix unit tests

* Style fix

* Compatible with fish_indent

* Use list for stability of order

* Sort one more place

* Sort more things

* Sorting unneeded

* Unsort

* Print difference

* Style fix

* Help messages need quotes

* Arguments to -a must be quoted

* Update types

* Update types

* Update types

* Add type hints

* Change order of positionals

* Always expand help

* Remove shared base class

* Fix type hints

* Remove platform-specific choices

* First line of help only

* Remove unused maps

* Remove suppress

* Remove debugging comments

* Better quoting

* Fish completions have no double dash

* Remove test for deleted class

* Fix grammar in header file
