Replace deprecated TiledCamera with Camera in visuotactile sensor

TiledCamera was merged into Camera in #5162, leaving TiledCamera as a
deprecated wrapper. The visuotactile sensor still used the old classes,
which caused CI failures due to the extra deprecation layer interacting
poorly with the refactored Camera renderer/Fabric initialization.

Also fix Camera.__del__ crash when __init__ raises before _renderer is
assigned by moving data attribute initialization earlier in __init__.
