Add additional scoping for head buffering

[matthewp]

Changes

• This is a continuation of Prevent eager rendering of head content in multi-level MDX layout #6107
• The idea is that when rendering to keep track of the scope with which a render occurs. We want to know that we are rendering JSX, or we are rendering Astro, or if we are rendering for head buffering.
• The conditional head injection uses this information to determine if it should render head content or defer.
• We know that when we are rendering JSX inside of an Astro layout that the Astro layout will do head injection, so we should not do it eagerly in the JSX content which will result in head content in the body.
• Closes MDX files with components insert script in layout slot #6057
• Closes Content collection MDX styles missing from prod builds for non-page components #6121

Testing

• New test case as provided by MDX files with components insert script in layout slot #6057

[bluwy]

Reading the changes, I think I understood the flow roughly 80%, but checking the logic I don't see anything incorrect, so putting an approval from me!

[matthewp]

@bluwy let me explain the flow for future readers then:

1. When calling JSX, Slots, head buffering (used to know what CSS to propagate), and slots.render(), append bit flags to result.scope.
2. Also created a scoped version of the result object (ie, Object.create(result)) so we can "lock in" result.scope so it applies only to children and not siblings.
3. In maybeRenderHead logic, use the bit flags to determine if we should render the head. The idea is that there are known scenarios where we should not; for example inside of a slot that's inside of JSX.

This all became necessary because of a combination of:

1. Implicit head injection.
2. Content collections and head propagation.

This code works but does add some bloat to the codebase that would be great to get rid of. For that reason I'm going to create a proposal that removes implicit head injection (likely in combination with a new feature like head propagation).
