[query] add local whitening method

[patrick-schultz]

~Stacked on #11045~

Implements a method to orthogonalize each row of (an entry field of) a matrixtable against all previous rows within a specified window size. The method has time complexity linear in the window size, and is blocked to arrange for most work to occur inside BLAS level 3 subroutines.

@patrick-schultz Are there any blockers to getting this PR in? It looks like it just needs a review and a merge.

I'll close in the meantime to alleviate some CI issues.

I'll be reviewing this shortly.

@tpoterba, I assigned to you in light of John C's departure.

It seems like this is realistically delayed until after the native compiler sprint. Is that a fair assessment, @patrick-schultz ?

[tpoterba]

rebase conflict and :shipit:

[danking]

@patrick-schultz I resolved the conflict by keeping main which seems to have encompassed your change but with a more descriptive error message.

@patrick-schultz bump
