DeepcopyDataflowAnalysis: make sure disabled calls do not cause issues

[MichaelSt98]

Description

This pull request adds support for disabling certain calls from being processed during the data offload deepcopy analysis, based on configurable pattern matching. The main changes introduce a mechanism to skip analysis for calls (such as error handler replacements) that match user-specified patterns, and include a new test to validate this behavior.

Dataflow Analysis Configuration

• The DeepcopyDataflowAnalysis class now accepts a disabled_calls argument, allowing users to specify call name patterns (using wildcards) that should be ignored during analysis. The logic for checking if a call is disabled is encapsulated in the new is_disabled_call method, which uses fnmatch for pattern matching.

• The DataOffloadDeepcopyAnalysis transformation class is updated to extract disabled call patterns from the transformation item configuration and pass them to the dataflow analysis. [1] [2]

Test Enhancements

• A new test fixture, deepcopy_abort_code, is added to provide source code and setup for testing the disabled call functionality.

• A new test, test_offload_deepcopy_analysis_ignores_unresolved_abor1_replacement, is added to verify that calls matching the disabled pattern (e.g., ABOR1*) are ignored by the analysis, ensuring that replacement error handler calls are not processed.

Dependency and Import Updates

• The fnmatch module is imported to support pattern-based matching of call names.
• The test imports are updated to include RemoveCodeTransformation.
