Configure fully qualified strict types fixer

[samuelmaudo]

This PR configures a rule for fully qualified symbol references.

With this change to its configuration, this code:

namespace Foo\Test;

class Foo extends \Other\BaseClass implements \Other\Interface1, \Other\Interface2
{
    /** @var \Other\PropertyPhpDoc */
    private $array;
    public function __construct(\Other\FunctionArgument $arg) {}
    public function foo(): \Other\FunctionReturnType
    {
        try {
            \Other\StaticFunctionCall::bar();
        } catch (\Other\CaughtThrowable $e) {}
    }
}

becomes:

namespace Foo\Test;

use Other\BaseClass;
use Other\CaughtThrowable;
use Other\FunctionArgument;
use Other\FunctionReturnType;
use Other\Interface1;
use Other\Interface2;
use Other\PropertyPhpDoc;
use Other\StaticFunctionCall;

class Foo extends BaseClass implements Interface1, Interface2
{
    /** @var PropertyPhpDoc */
    private $array;
    public function __construct(FunctionArgument $arg) {}
    public function foo(): FunctionReturnType
    {
        try {
            StaticFunctionCall::bar();
        } catch (CaughtThrowable $e) {}
    }
}

I have also removed the @see PHPDoc tag because we have several uses of this tag with fully qualified symbol references, and they refer to other classes that are not used in the class code.
