[Copilot] comp build should default to the same flow the render uses

[dmcilvaney]

Issue Description

Currently azldev comp build <pkg> uses the legacy source prep flow by default. We have moved to using rendered specs with synthetic dist-git history. This is a surprising discrepancy for users. We need to invert the logic to use the distgit flow by default when preparing sources or building packages.

Expected Changes

invert the --with-git flag and make it --without-git for all tools. Update/add tests to cover this change.
