Add encoding quality option to video processing functions

[Rajan-p-simform]

Developers can now choose the preferred performance mode for video operations, balancing between speed and output quality. We offer three modes:

• FASTEST – Optimized for speed; operations complete quickly but may result in lower output quality.

• BALANCED – Offers a middle ground between processing time and quality.

• HIGHEST – Prioritizes output quality; operations may take longer to complete.

This flexibility allows developers to adjust performance based on their specific use case.
