[SYCL] [MATRIX] Enable joint_matrix_load, joint_matrix_store, and

joint_matrix_mad for AMX

We provide new interfaces for matrix muliply in this patch:
1. A new class called joint_matrix is introduced, and the user needs to
specify the type of the elements, sizes, and the memory layout.

2. joint_matrix_load is used for loading data from main memory to tiles of
AMX or kernel's local memory.

3. joint_matrix_store is used for storing data tiles of AMX or kernel's
local memory to main memory.

4. joint_matrix_mad is used for the matrix multiply and add function.
It performs the multiply operation on the matrices A and B, accumulates the
result with C and returns the result.

With this patch, the following operation can be realized:
  C = A*B+C
1. All cases where A(int8, any-size, row_major), B(int8, any-size, packed_b), C(int32, any-size, row_major)
2. All cases where A(bf16, any-size, row_major), B(bf16, any-size, packed_b), C(float, any-size, row_major)
