[XPU] Add xpu support of make triton (#126513)

Browse Source 
This PR is to add XPU support for `make triton`.

If a user wishes to use Triton with XPU support, the user needs to install the  [intel-xpu-backend-for-triton](https://github.com/intel/intel-xpu-backend-for-triton).

This PR allows the user to easily install Triton for xpu backend support:

```
# clone the pytorch repo
export USE_XPU=1
make triton
```
The XPU version of triton will always be built from the source. It will cat the commit id from `.ci/docker/ci_commit_pins/triton-xpu.txt`, for example, `b8c64f64c18d8cac598b3adb355c21e7439c21de`.

So the final call would be like:

```
pip install --force-reinstall "git+https://github.com/intel/intel-xpu-backend-for-triton@b8c64f64c18d8cac598b3adb355c21e7439c21de#subdirectory=python"
```
