Added FPGA Register Programming + fixed P2P GPU Buffer Allocation

[mar-ven]

Description

This PR provides two contributions:

1. the FPGA register programming API (both driver and sw API) to enable GPU kernels to launch FPGA kernels
2. moved the P2P GPU buffer allocation process from HSA to HIP for better stability and improved performance

Type of change

• Bug fix
• New feature
• Documentation update
• A new research paper code implementation
• Other

Tests & Results

We tested the implemented feature and integrated a novel Coyote Example for FPGA register programming.

Checklist

• I have commented my code and made corresponding changes to the documentation.
• I have added tests/results that prove my fix is effective or that my feature works.
• My changes generate no new warnings or errors & all tests successfully pass.
