Reviewed by Dan Glastonbury.

Apple4 and Apple5 devices have Tier 1 AB support, not tier 2, but
their limits were set according to tier 1 limits.

These are mostly older phones and iPads (iPhone XS, 2018 iPad Pro),
so we can instead use the default WebGPU limits which many websites
may use in any case.

Apple3 is not supported by WebGPU core, rather only WebGPU compat mode, which we
don't have any validation for right now.
