fix(resolver): honor root self-provide/replace as require fulfilment

Port Composer's RuleSetGenerator::createRequireRule self-fulfilling
branch: when the root composer.json's `provide` or `replace` covers a
name it also requires (with intersecting constraints), skip emitting an
install-one-of rule for that root require. Composer relies on the root
package being a fixed entry in the pool so whatProvides() includes it;
Mozart does not yet add the root to the pool, so the same decision is
made via explicit `root_provide` / `root_replace` tables threaded
through ResolveRequest. Without this, an inline repo package whose name
matches the root's provide was being force-installed.

Fixes installer fixtures `provider_satisfies_its_own_requirement` and
`replacer_satisfies_its_own_requirement`.
