[Triton] Triton generated kernel cannot be load correctly thru the L0 API.

[chengjunlu]

One very large Triton kernel cannot be load correctly thru the L0 API.
Got the error code 0x78000011 from L0 API zeKernelCreate.

ZE_RESULT_ERROR_INVALID_KERNEL_NAME = 0x78000011,   ///< [Validation] kernel name is not found in the module

We double confirmed that the kernel name is used correctly same as the one in the SPIRV IR.

A simple c++ unit test for reproducing this issue.

You can use the following command to build and run the test under the root director of the code:

mkdir build
cd ./build/
cmake ../ -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=dpcpp
make all
./test_void_kernel/triton_void_kernel

On ATSM platform result:

@silee2 ,
I find in your log there is the triton__0d1d2d3d4d5d6d7d8d9d10d11d12d13d14d15d16d17d18d19d20d21d22d23d24d25d26d27d28d29d30d31d32d33d34d35d36d37d38d39d40d41d42d43d44d45d46d47d48d49d50d51d52d53d54d55d56d57d58d59d60d61d62d63d64d65d66d67d68d69d70d71d72d73d74d75d76d77d78d79d80d81d82d83d84d85d86d

It means the L0 module has been loaded correctly and we can iterate the kernel in the module.

But in my platform, the L0 module is created without the kernel.
