Prefer ProjectFlags over additional field in OutdatedFlags

Since most commands use 'ProjectFlags' but almost all commands can not
function properly without a project context, some commands manually
strip the flag '-z' (--ignore-project) from the command line option parser.

Unify the behaviour for all commands.

Allow relative paths starting with single-character directories

Add changelog for #7413 (Fix instantiating an indefinite Backpack from Hackage with an inplace package)

Modernise `outdated` command

Reformat imports and data declarations.
Remove old code-paths from `cabal-install/src/Distribution/Client/Setup.hs`
Remove unnecessary parentheses.
Mirror command structure from other Commands.

Cabal outdated should not list deprecated versions

Because cabal2nix and haskell.nix work at all, I'm confident the new
comment is also more correct as to how this function is used in
practice.

Use `hs-source-dirs` for the library and change the `other-modules`
names for the executables to avoid confusion.

Lowercase the `main-is` files to make it clear the filename need not be
a module name.

Add dependency on the internal library to the prog2 executable to
showcase common usage.

The simple package examples share module names among library and
executable components. To avoid potential confusion these have been
annotated to make it crystal clear the modules do not refer to the same
entities.

Changes the behavior of the following commands under the `--dry-run` and
`--only-download` flags
- `v2-configure` and `v2-freeze` do not write their respective files
- `v2-exec` and `v2-run` do not run the target executable

Adds package tests for the configure and freeze commands.

This commit straightens the v2-configure command:

* Removes the pre-build phase
* Adds two flags, --append and --overwrite

Fixes the bug by accurately tracking when instantiations refer to
inplace packages, and adjusting previously non-inplace packages to be
inplace when this occurs.  See comment in ProjectPlanning.hs for more
details.
