refactor: use chainman instead of chainParams for DeploymentActive*

Summary:
This is a partial backport of core#24595

We don't have a g_versionbitscache global, and the point of the PR in the source material is to make that global a ChainstateManager member. The only rationale for backporting this in Bitcoin ABC is to make following backports easier (for instance in core#25704 one of the functions touched here will use the chainman argument)

Depends on D15808

Test Plan: ninja all check-all
