Pull Request Overview
This PR resolves memory management bugs in the QNN (Qualcomm Neural Network) execution provider when VTCM (Vector Tightly Coupled Memory) backup buffer sharing is enabled. The changes address vector reallocation issues and handle processing of new binary contexts.
Key changes:
- Pre-allocates memory for context parameter lists to prevent memory corruption during vector resizing
- Adds logic to detect and handle new binary contexts that haven't been processed yet
