In haskell#10292, we will move the `--keep-temp-files` setting into
`CommonSetupFlags` and out of `ReplFlags`/`HaddockFlags`. This means
that the flag-filtering behavior (which adapts flags from new versions
of `cabal-install` to old version of `Cabal`) will need to know which
command is being run to provide the correct `CommonSetupFlags`.

Therefore, this change adds several new `filterFooFlags` functions to
provide this behavior, and removes the `commonFlags` used for all
subcommands in `Distribution.Client.ProjectBuilding.UnpackedPackage`.

`addFields` should be in `ParseUtils` with the rest of the field
helpers.

Currently, `cabal repl` has a `--keep-temp-files` option, and
`cabal.project` has a `keep-temp-files` option but it only effects
Haddock builds.

This patch adds `--keep-temp-files` to `CommonSetupFlags`, making it
available to all commands. The expanded `--keep-temp-files` flag is used
for the `cabal repl` command and Haddock builds (retaining compatibility
with the previous behavior) but is also used to determine when to keep
response files.
