Refactor prompt validation and code processing in Component and PromptComponent classes #2264

Adds a post_code_processing method that runs right after the component code is validated. The previous logic was moved into the Component class and classes that override this method should call the super() class almost always.

Components can now define post validation logic such as setting values dynamically when updated.

This PR also fixes the PromptComponent not being allowed to update its code.

Additionally, refactor the prompt validation process in the validate.py.

Refactor the prompt validation process in validate.py to improve code readability and maintainability. The changes include:

- Update the import statement for process_prompt_template in api_utils.py.
- Remove unused imports from api_utils.py.
- Simplify the post_validate_prompt function by removing unnecessary conditional statements.
- Replace the validate_prompt function call with process_prompt_template in post_validate_prompt.

These changes enhance the efficiency and organization of the prompt validation process.
When updating the Component code in GenericNode, handle any errors that occur. If an error occurs, display an error message with instructions to report the issue on Discord or GitHub. This improves the error handling and user experience when updating the Component code.
Refactor the post_code_validation method in the Component class to improve code readability and maintainability. The changes include:

- Rename the parameters to better reflect their purpose.
- Update the function documentation to provide a clear explanation of the method's purpose.
- Remove unnecessary comments and whitespace.
- Improve variable naming for better clarity.

These changes enhance the overall quality of the code and make it easier to understand and maintain.
Update the return type of the build_custom_component_template function in utils.py to include the possibility of returning a Component object. This change ensures that the function can handle both CustomComponent and Component objects, improving flexibility and compatibility.
The post_code_validation method in the Component class has been renamed to post_code_processing to better reflect its purpose. This change improves code clarity and maintainability.
Refactor the post_code_processing method in the PromptComponent class to improve code readability and maintainability. The changes include:

- Import the process_prompt_template function from langflow.base.prompts.api_utils.
- Import the update_template_values function from langflow.template.utils.
- Call the process_prompt_template function to update the template value.
- Update the frontend_node with any values set in the current_build_config.
- Remove unnecessary comments and whitespace.

These changes enhance the overall quality of the code and make it easier to understand and maintain.
