The conversion from `concatMapStrings` to `concatStringsSep` introduced in https://github.com/nix-community/home-manager/pull/2481
creates an unintended behavior change where the formatted config does not end in a newline.[1]
This is problematic for manipulation at the Nix level. In particular, this cause a regression in
the generation of gtk2 settings due to concatenated of the formatted config and `gtk2.extraConfig`
without a newline in between.
This commit restores `concatMapStrings` to match the previous behavior and adds a newline to
the final string for the generated gtk2 config. The test case for gtk2-basic-config
was also updated to check behavior at concatenation boundaries.

* gtk: add cursor theme configuration
- Added the `cursorTheme` under the gtk module.
- Added tests for the gtk3 settings file generation, and renamed
the gtk2 unit test expected file for clarity.
- Added guard against generating a blank `gtk.css` when `cfg.extraCss`
is empty.
- Replaced `concatMapStrings` calls with `concatStringsSep`. The library function
`concatMapStrings` generates an intemediate list which is then passed to
`concatStringsSep`, As we are not performing other transformation except
the addition of newlines, a direct call to `concatStringsSep` is sufficient.
- Updated description of examples to be more general "~/.config" -> "$XDG_CONFIG_HOME".
- Update helper functions `toGtk3Ini` and `formatGtk2Option` to use the library
function `boolToString` and escape the separator in the key name.
* xcursor: delegate GTK cursor settings to gtk.cursorTheme
- Added deprecation warning for GTK settings in the `xsession.cursorTheme` module.
- Modified config section to use `gtk.cursorTheme` for GTK cursor settings.
Currently, dot directories and XDG base directories are used
inconsistently in the Home Manager option declarations. This creates
ambiguity for the user as to where the location of the file should be
albeit this is rarely encountered in practice as it is sufficient to
read upstream documentation. The rationale is to make declarations
consistent and make a clear distinction between hardcoded and modular
specifications.
References to ~/.config in relevant nixpkgs modules were untouched as
the location is hardcoded upstream[1]. Furthermore, modules of
programs which do not follow XDG specifications were also untouched.
Generalization of tilde(~) expansions to $HOME were also considered,
however there isn't sufficient rationale despite the use of $HOME
being more universal. The expansion is standardized in POSIX[2] and is
essentially portable across all shells, thus there is no pragmatic
value to introducing the change.

Add a new 'bookmarks' option, for managing `~/.config/gtk3/bookmarks`,
a list of URIs to display as bookmarks in the sidebar of GTK file
browsers.
