Implement GPU mining backends for three new algorithms:
- ProgPowZ (Zano): DAG-based ProgPow variant with 512 parents, dynamic
program generation per period
- ETChash (Ethereum Classic): Standard Ethash with 256 parents and
ECIP-1099 epoch calculation for post-block 11.7M
- Blake3DCR (Decred): Simple Blake3 hash kernel with no DAG requirement,
processing 180-byte block headers
Each implementation includes OpenCL kernels, GPU runners, thread
generators, and build system integration. Also adds fast modulo
optimization to ETCCache for GPU kernel performance.

- Add GPU config fields: GPUEnabled, GPUPool, GPUWallet, GPUAlgo, CUDA, OpenCL
- XMRig config now supports separate pool/algo for GPU vs CPU mining
- CPU can mine RandomX while GPU mines KawPow on different pools
- Add xmrig_gpu_test.go with tests for dual, GPU-only, and CPU-only configs
- Make getXMRigConfigPath a variable for test overriding
