SPIR-V Tools fuzzer: check binary size

Adds assertions to check that the SPIR-V Tools fuzzer is not
inadvertently applied to SPIR-V binaries of an invalid size, which
guards against the fuzzer being run in a misconfigured fashion.

The CL also moves a memcpy that populates a SPIR-V binary buffer so
that the memcpy only happens when the input really is SPIR-V. This
avoids frequent redundant memory copies when fuzzing WGSL.
