fix(openapi): enhance embedded field processing to respect swaggerignore tag

[manusa]

Description

Related to #7371 #7386 #7376

The root-cause of the issue is the fact that the type processing in

kubernetes-client/kubernetes-model-generator/openapi/generator/pkg/openapi/openapi-gen.go

Lines 98 to 109 in eb8eee4

	for _, pkg := range context.Universe {
	for _, t := range pkg.Types {
	for memberIndex, member := range t.Members {
	for _, memberProcessor := range g.memberProcessors {
	memberProcessor(context, pkg, t, &member, memberIndex)
	}
	}
	}
	for _, packageProcessor := range g.packageProcessors {
	packageProcessor(context, pkg)
	}
	}

doesn't follow a deterministic order.

Since the processInlineDuplicateFields processes the child embedded type members, it might be the case that one of these members hasn't been processed by the processSwaggerIgnore processor yet.

After multiple iterations trying to find a simpler+granular solution, I couldn't come up with the granular one that preserved simplicity.
Keeping things granular and focused (i.e. not considering the swaggerignore tags in the inlineduplicatefields processor) requires adding too much complexity to the code which in the ends defeats the simplicity purpose.
