Support regex filters for listing table paths

[osipovartem]

Summary

• add an optional precompiled full object-path regex to ListingTableUrl
• apply regex filtering to the object metadata stream before files are planned or opened
• make regex and glob matchers mutually exclusive
• dispatch once when constructing the listing stream so the existing default/glob hot path does not pay a per-object regex branch

This is intended for consumers that need regular-expression file selection over object-store prefixes, such as Snowflake-compatible staged COPY INTO ... PATTERN handling. It avoids an application-side LIST followed by one HEAD request per selected object.

Validation

• cargo +1.95.0 test -p datafusion-datasource (180/180 unit tests, 8/8 doctests)
• cargo +1.95.0 clippy -p datafusion-datasource --all-targets -- -D warnings
• cargo +1.95.0 fmt --all --check

Tests cover prefix isolation, nested-path regex selection, glob replacement, and filtering through the real list_all_files metadata stream.
