IBX-8032: Added proper casting to int for width/height in image search field

[konradoboza]

🎫 Issue	IBX-8032

Description:

This PR is about adding integer casting for width/height values to work with SearchField::getOrientation() method. It seems some legacy data might fail as strict typing is introduced here. However, the old way of composing index like

new Search\Field(
    'width',
    $width,
    new Search\FieldType\IntegerField()
),

is less forgiving and accepts some "wider spectrum" of types.

For QA:

Since there is no easy way to reproduce the issue I think sanities will do in this case.
