[ROCm] support optimized Stable Diffusion model (#14980)
Add BiasSplitGelu/BiasAdd/GroupNorm/NhwcConv operator for ROCm EP.
1. BiasSplitGelu and BiasAdd operators can be automatically hipified
from CUDA EP.
2. GroupNorm was hipified from CUDA EP and modified to build.
3. NhwcConv is similar to NhwcConv in CUDA EP, But the MIOpen API and
cuDnn API are different. `miopenConvolutionForwardbias` and
`miopenOpTensor` of MIOpen doesn't support NHWC layout now, use
BinaryElementwise to replace miopenConvolutionForwardbias(NHWC layout).
