msl: Add ArrayLengthFromUniform transform Generate a uniform buffer that will receive the lengths of all storage buffers, and use this to implement calls to arrayLength(). The transform is provided with a set of mappings from storage buffer binding points to the corresponding index into the array of buffer lengths. The transform reports whether it generated the uniform buffers or not. Use this transform from the MSL sanitizer, using the binding number as the index into the array. This matches the behavior of spirv-cross, and so works with how Dawn already produces this uniform buffer.

Make ArrayLengthFromUniform transform emit a valid UBO The UBO must have a stride that is a multiple of 16 bytes. Note that this change was part of https://dawn-review.googlesource.com/c/tint/+/56780 but the CL was reverted because it broke Dawn. This CL relands part of the change, and adds the macro TINT_EXPECTS_UBOS_TO_BE_MULTIPLE_OF_16 so that Dawn can conditionally compile against it.
