bf16_to_float: Fix strict aliasing violation

* This function was accessing a uint32_t with a pointer to float which
violates the strict aliasing rules. With GCC 11, this leads to a
-Wuninitialized warning, which causes the build to fail.

* This change uses memcpy instead of type punning which fixes the strict
aliasing violation, thereby fixing the build with GCC 11.

* Resolves MLCE-420
