[simdjs] Implement type check and error raising in SIMD runtime functions.

Implement type check and error raising semantics in SIMD runtime functions.
 - Throw type errors instead of runtime asserts.
 - Also required for SIMD tests ported to Test262 to work with V8

File src/runtime/runtime-simd.cc (right):

This throws a SIMD-specific error, so maybe it should have a name related to
SIMD. Also, doesn't it shadow another macro? Better to use a different name.
