Backport of #110057 to release/9.0-staging
/cc @tannergooding @hez2010
Customer Impact
#110050. Customers using Matrix4x4.CreateReflection may see incorrect results on some hardware.
Regression
#103527. The code was updated to be accelerated and had an edge case where all components were scaled by -2 instead of just the X, Y, and Z components.
Testing
An explicit test covering the scenario where the W component was non-zero was added.
Risk
Low. This is in an API that is primarily used in specialized scenarios.
