NoBlankLineBetweenImportsFixer collapsed every blank line between consecutive top-level use statements, including the one separating a class-import group from a use function / use const group.

Now the blank line is kept whenever adjacent imports differ in kind (class vs function vs const), in both directions. Blank lines within the same group are still collapsed.

Before:

use Foo\Bar;

use Foo\Baz;

use function Foo\first;

After:

use Foo\Bar;
use Foo\Baz;

use function Foo\first;

Applied to both the PHP fixer and the Go (blink) port, with tests for each.
