Make ApiExplorer for minimal APIs trim-compatible

This PR introduces new API and behavior modifications to support making the entire OpenAPI pipeline for minimal APIs in ASP.NET Core trimming and native AoT-compatible.

Description

Changes introduced in this PR include:

• Introduction of IParameterBindingMetadata API
• Updates to RequestDelegateGenerator and RequestDelegateFactory to support emitting IParameterBindingMetadata for each endpoint
• Updates to RequestDelegateGenerator and RequestDelegateFactory to support emitting response metadata for handlers that return awaitable responses
• Updates to ApiExplorer for minimal APIs to support consuming IParameterBindingMetadata and response metadata
• Updates to ModelMetadata in MVC abstractions to support trim and AoT-compatability

Fixes #56023

Customer Impact

Native AoT support is a differentiation for built-in OpenAPI support and allows us to continue our commitment to make new features for minimal API native AoT-compatible by default.

This changeset carries medium risk, so we'd like to merge it into preview.7 to identify any potential issues related with the changes including:

• Changes in the API Explorer-layer with regard to how parameter binding metadata is resolved
• Changes in the code generation layer for minimal APIs when publishing with and without AoT
• Changes in MVC's abstractions layer to make dependent types trim and AoT-compatible

Verification

• Manual (required)
