Closes #536

Description

This adds proper error detection to creation of mesh, skeleton, and texture creation. This should eliminate the majority of unexpected crashes from allocation failures.

Allocation failures that are handled by WebGPU itself cannot currently be handled due to the asynchronousness of errors. On native they will be caught as expected.
