ASTGen: prevent _StringProcessing from being loaded

compnerd · compnerd · commit 7a03e8ffc8d2 · 2025-09-04T10:00:16.000-07:00
When building the ASTGen library, we are building `_StringProcessing`.
If the SDK version is loaded, it causes confusion over the local
definition and the SDK definition. Avoid the implicit loading of the
module.
