remove *(A::Matrix, B::HermOrSym) = A*full(B) (#22373)
- this dispatches to BLAS instead
- seems a tiny bit faster
- allocates half of the memory
- main reason is to be consistent with the opposite method
e.g. *(A::HermOrSym, B::Matrix) which does no longer have this
fallback method with a full call, but dispatches to
BLAS.symv!/BLAS.hemv! directly
only call full on second argument for *(A::HermOrSym, B::HermOrSym)
