Add AMD AIE1 CGRA support with ACAP++/AIE++ and ArchGenMLIR for FPGA

[keryell]

• Add compiler support for AMD AIE1 CGRA.
• Provide ACAP++ and AIE++ SYCL extensions for AMD AIE1.
• Provide ArchGenMLIR tool for FPGA SYCL to automatically generate approximations for mathematical fixed-point functions to optimize hardware usage for low precision computations.
