[BUGFIX] Allow user defined locales to work with TSFE->sL()

TYPO3 uses a list of "known" languages defined in
TYPO3\CMS\Core\Localization\Locales.

This list can be extended by the user, but these changes
are not taken into account when using
$GLOBALS['TSFE']->sL() to fetch the translation.

Make TypoScriptFrontendController call the needed method
"initialize()" to make it work.

[BUGFIX] Remove the need of PackageStates.php in tests

Although there is code in the package manager tests
to mock a PackageStates.php file, it does not work
as the path to the file is hardcoded in the initialize
action.

Move the code for setting the path and creating
the package factory to the constructor
and move the mocking of the path before initializing
in the test.

[BUGFIX] Backup of LocalConfiguration.php missing on update

If you update from a 6.x installation there should be a backup of the
old, unmodified LocalConfiguration.php as it's getting changed during
PackageStates.php extraction. This is prevented with commit e755bcd
as a check for the PackageStates.php file was introduced, which might
not be available at this point during upgrade.

[BUGFIX] Do not reset Page Renderer on partial rendering

Currently the Page Renderer is reset when calling
the render() method, even if only one part (header
or footer) is rendered, which causes a second call
to fail, when rendering another part.
This happens e.g in DocumentTemplate.php where
the render() method is called two times. Because of
the reset, the second call starts pageRenderer with
empty properties.

Solution is to only call reset if everything is rendered.

[BUGFIX] Fetch RSA public key by Ajax before login

Currently public and private RSA keys are generated when rendering the
login form. This has several drawbacks.

It can lead to strange and hard to debug errors when a second request is
done in the same browser, which invalidates the key for the current
login form (#38660), opening a second login in a different tab
invalidates the key on the first tab and finally when the login form
stays open until the PHP session expires (parts of the private key are
stored in the PHP session), the key is also invalid for the form.

Solution is to create a new key pair on the fly when a user clicks the
submit button and fetch the public key via Ajax.

This change implements this for the backend login. Frontend login should
be tackled in a different patch.
