i386: Introduce module level cpu topology to CPUX86State

Intel CPUs implement module level on hybrid client products (e.g.,
ADL-N, MTL, etc) and E-core server products.

A module contains a set of cores that share certain resources (in
current products, the resource usually includes L2 cache, as well as
module scoped features and MSRs).

Module level support is the prerequisite for L2 cache topology on
module level. With module level, we can implement the Guest's CPU
topology and future cache topology to be consistent with the Host's on
Intel hybrid client/E-core server platforms.
