feat(datafusion): support bool and numeric schema evolution to Utf8

[haohuaijin]

Depends on #9261 and should remain in draft until that PR is merged.

Summary

• Accept Bool and numeric physical columns under a unified Utf8 or LargeUtf8 schema.
• Preserve each file physical type so the expression adapter can insert the cast to the logical string type.
• Keep numeric and Bool columns incompatible with Binary and LargeBinary schemas.

E2E coverage

The schema-evolution test covers the complete progression:

• Int64 schema reads Bool and Int64 files.
• Float64 schema reads Bool, Int64, and Float64 files.
• Utf8 schema reads Bool, Int64, Float64, and Utf8 files.

Each stage verifies full scans and filtered queries with projection pushdown both enabled and disabled.
