Move Linux GPU CI pipeline to A10 (#23235)
Move Linux GPU CI pipeline to A10 machines which are more advanced.
Retire onnxruntime-Linux-GPU-T4 machine pool.
Disable run_lean_attention test because the new machines do not have
enough shared memory.
```
skip loading trt attention kernel fmha_mhca_fp16_128_256_sm86_kernel because no enough shared memory
[E:onnxruntime:, sequential_executor.cc:505 ExecuteKernel] Non-zero status code returned while running MultiHeadAttention node. Name:'MultiHeadAttention_0' Status Message: CUDA error cudaErrorInvalidValue:invalid argument
