physicalplan: add support for multi-stage execution of regr_avgx, reg…

…r_avgy,

regr_intercept, regr_r2, and regr_slope aggregate functions.

See cockroachdb#58347.

Release note (performance improvement): regr_avgx, regr_avgy, regr_intercept,
regr_r2, and regr_slope aggregate functions are now evaluated more efficiently
in a distributed setting
