Avoid requiring a minVersionForCollab when codec write version selection is not needed.

[CraigMacomber]

Description

We have a few places in our code where we don't actually need to select a write version, but require providing all the information needed to do so.

This change tweaks the types a bit and adds a buildDecoder option, removing the neww for thisunnecessary data.

Pull request overview

This PR reduces required inputs when only decoding versioned persisted data by introducing a decoder-only build path, and updates several schema-related call sites/tests to use it instead of forcing minVersionForCollab-driven write-version selection.

Changes:

• Generalize ClientVersionDispatchingCodecBuilder build options to ICodecOptions and add buildDecoder(options) for decode-only scenarios.
• Update schema decoding call sites to use schemaCodecBuilder.buildDecoder(options) instead of supplying a dummy minVersionForCollab.
• Update schema codec tests to stop passing minVersionForCollab when constructing per-format codecs.
