Wyatt Johnson 8abbb3dc2e refactor: rename experimental.dynamicIO to experimental.cacheComponents (#81562)
## What?

Rename `experimental.dynamicIO` to `experimental.cacheComponents` across
the Next.js codebase.

## Why?

We're going to be merging the functionality of the `ppr`, `dynamicIO`
and `useCache` experimental flags into the singular `cacheComponents`
flag to reduce complexity of the codebase and simplify adoption for
users wanting to experiment with experimental features.

## How?

- Renamed the configuration option from `experimental.dynamicIO` to
`experimental.cacheComponents`
- Added deprecation handling with automatic migration for the old option
name
- Updated all documentation, tests, and internal references
- Updated Rust code in SWC transforms and Turbopack
- Maintained backward compatibility with deprecation warnings
