Camera Tracking: allow fallback to reprojection resection by user demand

This fixes some "regressions" introduced in rev50781 which lead to much
worse solution in some cases. Now it's possible to bring old behavior back.

Perhaps it's more like temporal solution for time being smarter solution is
found. But finding such a solution isn't so fast, so let's bring manual
control over reprojection usage.

But anyway, imo it's now nice to have a structure which could be used to
pass different settings to the solver.
