auto create file column if it doesnt exist

[zhaodongwang-msft]

updated upload_file function to auto create the file column if it doesn't exist. also included some minor improvments like supporting file column in create_column

Copilot summary:
This pull request introduces improvements to the file upload workflow, focusing on making the upload_file method more robust and user-friendly. The most significant enhancement is the automatic creation of a file column if it does not exist when uploading a file, along with waiting for the new attribute to become visible before proceeding. Additional changes include code cleanup in the advanced file upload example and improved documentation.

File upload improvements:

• The upload_file method now automatically checks if the specified file column exists; if not, it creates the column and waits for it to become visible in the data API before uploading the file. This ensures smoother uploads without manual column setup. [1] [2] [3]
• The signature and documentation of _upload_file have been updated to use table_schema_name instead of entity_set, reflecting the new workflow and clarifying parameter expectations. [1] [2]
• The upload_file method in client.py now passes table_schema_name directly, simplifying the call chain.

Documentation updates:

• Usage examples in README.md and skill documentation files now clarify that the file column will be created automatically if it doesn't exist. [1] [2]

Example and code cleanup:

• The advanced file upload example (file_upload.py) was refactored for clarity: variable initialization order was improved, the table schema name was updated for testing, log statements were made dynamic, and redundant attribute creation logic was removed (as this is now handled automatically by the upload method). [1] [2] [3] [4]
