Document block-level evaluation of LossFunction

Note in LossFunction::Evaluate docs that s = ||f_i||^2 is the squared norm of the entire residual block rather than its individual scalar components, and add a modeling FAQ explaining why independent measurements should be placed in separate ResidualBlocks when using a LossFunction.

Fixes https://github.com/ceres-solver/ceres-solver/issues/264
