Moves the Mathlib pin from the v4.36.0-rc2 tag (9d581df) to 1b1ccf4,

LMLExplore builds LML against this Mathlib, where LML's uses of
`Measure.coe_add`, `Measure.coe_zero`, `Measure.smul_apply` and
`Measure.finsetSum_apply` are deprecated. The warnings fail LMLExplore's
strict PR builds.

Use the generic `FunLike.coe_add`, `FunLike.coe_zero`, `smul_apply` and
`sum_apply`. `Kernel.sum_apply` is now protected, so name it in full.
`Kernel.compProd`'s body is no longer exposed, so prove `compProd_lift`
from `compProd_apply` instead of unfolding the definition.
