[SYCL][Joint Matrix][E2E] Remove xfail from Joint Matrix runtime dimension tests (#15784)

Description: 
The failure of the tests joint_matrix_bf16_fill_k_cache_arg_dim.cpp and
joint_matrix_bf16_fill_k_cache_runtime_dim.cpp has been addressed in
commit
intel/intel-graphics-compiler@92236dc.
The commit solves the issue by changing the Acc 32x64 and Acc 32x32
matrix types from using the array type [2 x <float x 64>] to a structure
type { <float x 64>, <float x 64> }
