[Internal] Remove variant_id in all executor related logic.

[thy09]

Description

Remove variant_id concept in all executor related logic since it is used only for legacy logic.

This pull request primarily involves the removal of variant_id from various methods across multiple files in the src/promptflow/promptflow/ directory. The variant_id parameter was previously used in the initialization, copying, and execution of flow runs and node runs, but it has now been removed from these processes.

Removal of variant_id from FlowExecutionContext:

• src/promptflow/promptflow/_core/flow_execution_context.py: Removed variant_id from the __init__ method, copy method, _prepare_node_run method, and bypass_node method. [1] [2] [3] [4]

Removal of variant_id from RunTracker:

• src/promptflow/promptflow/_core/run_tracker.py: Removed variant_id from the start_flow_run method and bypass_node_run method. [1] [2] [3] [4]

Removal of variant_id from FlowExecutor:

• src/promptflow/promptflow/executor/flow_executor.py: Removed variant_id from the exec method, exec_line method, exec_line_async method, _exec method, and _exec_async method. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
