PSR2.Namespaces.UseDeclaration.SpaceAfterUse should also check for space after use const/use function

[umherirrender]

If you have the following code:

use\Import\SomeClass;
use const\Import\SomeConst;
use function\Import\SomeFunction;

there is no hint to add a space after const or function.

Good: When using multiple spaces between use and const, it is detected.

Because of the reasons detailed in #2961 (comment), I believe this issue should be closed. const\Import\SomeConst and function\Import\SomeFunction are seen by PHP and PHPCS as a single T_NAME_QUALIFIED token, so there is no easy way for PHPCS to trigger PSR2.Namespaces.UseDeclaration when it finds the code above. Not to mention that the code above is valid, and adding the space would change its behavior.
