native,testlapack: reduce required length of wr and wi in Dlahqr
...
Dlahqr must not (and does not) write into wr and wi beyond ihi, so it only makes
sense to make the slices shorter. Dlaqr4 (the caller) will have the same restriction.

native: check input slices to Dlaqr2, Dgehrd and Dormhr only after workspace query
...
so that it is possible to pass all slices as nil to those functions. A workspace
query should depend only on the input sizes, the matrices and vectors must
not be accessed anyway or may not be available at the call site. Moreover, often
the reference LAPACK uses arbitrary placeholders for arrays and relies on the
fact that no checking is done.

native: add indicator of convergence to returned values from Dlahqr
...
Previously, the zero value of the returned integer info was used to indicate
success. This is wrong because it is a 0-based index unlike the reference LAPACK
where it is a 1-based index and therefore 0 is available for such purpose. This
commit adds `converged bool` to the returned values from Dlahqr.
