[SYCL][ESIMD][EMU] Marking ESIMD kernels for esimd_emulator backend (#751)

- 'vadd_1d' and 'sycl_esimd_mix' are duplicated to
'esimd_check_vc_codegen.cpp' and 'sycl_esimd_mix_check_build_opts.cpp'
so that original kernels can run with esimd_emulator without 'CHECK'
commands and duplicated kernels can run with opencl/level_zero
backends with 'CHECK'
- Add XFAIL/UNSUPPORTED markup for 
    - Unimplemented features
    - Outdated memory intrinsic implementations
- Reduce workset in matrix_transpose_glb.cpp when running on esimd_emulator 
- Removing HOST_RUN_PLACEHOLDER for ESIMD Kernels
