EmbeddedResource returns a single content block, ReadResourceResult returns an array

Is your feature request related to a problem? Please describe.
EmbeddedResource delivers a content block and a uri, where the uri can be used to re-fetch later via resources/read. However, the result of the latter (a ReadResourceResult) delivers an array of content blocks.

Practical consequence is that EmbeddedResources can't embed the full content of multi-block resources.

Less practically, it's an inconsistency in the "EmbeddedResources are pre-fetched Resources, with a uri for re-fetching" high-level design.

Describe the solution you'd like
Modify EmbeddedResource to deliver an array of content blocks.

Describe alternatives you've considered
Leave it alone.

先从协议规范中 EmbeddedResource 和 ReadResourceResult 的定义开始，然后比较它们各自如何表示内容块。检查规范项目中的任何相关 schema 示例或生成的类型。完成的标准是两种资源表示保持一致，并且可以嵌入多块资源而不丢失内容。
