New description:
Adds an exact routine, and a numerical routine, to determine if a matrix
is Hermitian.
Apply trac_10848-hermitian-matrices-v5.patch
Depends on #10536, #11027

Comment:
v5 patch is self-contained, apply only this one.
Two options for the check, the naive one, or one based on the Schur
decomposition (#11027).
This needs to check that the upper half of a matrix is zero, so I broke
out a helper method for that, since I'll use it in a future `is_normal()`
method. I might pair it with an upper-triangular check at some point and
make them both visible. But not as part of this.
