[WIP] Improve pyarrow-free remote-IO performance

[rjzamora]

Description

Improves fsspec-only behavior for multi-file and partial reads from remote storage. Host-memory usage will be suboptimal compared to NativeFile (for now), but performance will be comparable in most cases.

This PR also includes deprecations for pyarrow-based IO. However, #16132 should take priority for the deprecations (and this PR should be modified accordingly).

TODO

• Needs cleanup
• Must be revised to depend on Deprecate Arrow support in I/O #16132. Also, dask-cudf open_file_options deprecation should probably be pulled out and merged before both 16132 and this PR.

Checklist

• I am familiar with the Contributing Guidelines.
• New or existing tests cover these changes.
