fix: Agent Component update_build_config, Nvidia and other model dynamic parameter loading

[edwinjosechittilappilly]

This pull request focuses on simplifying the handling of input field prefixes and enhancing the update logic for build configurations within the agent.py file. The most important changes include removing prefixes from input field names and updating the build configuration logic to be more modular and maintainable.

Simplification of Input Field Prefixes:

• src/backend/base/langflow/base/models/model_input_constants.py: Removed prefixes from input field names in the create_input_fields_dict function and updated related dictionary entries accordingly. [1] [2] [3]

Enhancements to Build Configuration Logic:

• src/backend/base/langflow/components/agents/agent.py: Added logic to call the update_build_config method of component classes if they exist, ensuring that the build configuration is updated correctly based on the selected provider. [1] [2] [3] [4]

@ogabrielluiz @anovazzi1 can you check why a lot of frontend test are failing in this PR?
