build: deprecate non all-in-one binary

[xxchan]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

• For production or for development, all-in-one binary is both preferred.
• fix(udf): add embedded-python-udf feature and fix dockerfile #15328 adds feature flag, but not added for non all-in-one binary. This indicates that it may bring unnecessary trouble for us.

Checklist

• I have written necessary rustdoc comments
• I have added necessary unit tests and integration tests
• I have added test labels as necessary. See details.
• I have added fuzzing tests or opened an issue to track them. (Optional, recommended for new SQL features Sqlsmith: Sql feature generation #7934).
• My PR contains breaking changes. (If it deprecates some features, please create a tracking issue to remove them in the future).
• All checks passed in ./risedev check (or alias, ./risedev c)
• My PR changes performance-critical code. (Please run macro/micro-benchmarks and show the results.)

• My PR contains critical fixes that are necessary to be merged into the latest release. (Please check out the details)

Shouldn't we still need to consider this for risectl after this PR? 😕

We can inline these variables.

risectl only requires minimal features, mainly some data types, so this is less likely a concern
