[WebGPU] A retained MTLSamplerState can result us in exceeding the
MTLSamplerState limit
https://bugs.webkit.org/show_bug.cgi?id=279542
radar://135708279
Reviewed by Dan Glastonbury.
We were tracking internally the number of samplers to ensure we didn't exceed
the process limit for MTLSamplerState instances.
This is problematic when a MTLSamplerState is retained outside the cache, e.g.,
in a pending MTLCommandBuffer.
Handle this by overriding dealloc in order to track the real alive count.
