[Naming] review demo projects names

I think device-class aware loading should be renamed to device-class aware code-splitting.
I think we might need to rename like resource loading, code-splitting, data-fetching. That is, just loading → resource loading since I think it sounds like loading covers more range including resource loading.

cra-memory-considerate-loading -> cra-memory-considerate-code-splitting or cra-memory-considerate-resource-loading because both mode are used here.

FYI: I found this issue while writing Recipes section in hooks/README.

This idea sgtm. Let's tackle after we land the README changes?

@addyosmani
Yes for sure. No problem.
