[SYCL][ESIMD][EMU] Enable dpas with ESIMD_EMULATOR backend

[dongkyunahn-intel]

• +fix for 'saturate<>' for ESIMD_EMULATOR backend

[dongkyunahn-intel]

Note : DPASW support will be enabled later as it requires updates in esimd_emulator backend interface as well as CM_EMU library for runtime support

Thanks @dongkyunahn-intel, do you know anything about SYCL :: unused_spec_const.cpp ?

@pvchupin , as far as I know 'spec_const' tests are disabled for ESIMD_EMULATOR backend as they are failing with Unsupported 'online_compiler' error. It could be because of 'AOT' that is not supported by the ESIMD_EMULATOR backend. Currently, there is no plan for enabling those tests with the backend.

Function signatures for __esimd_dpas* will be changed to have precision, systolic depth, and repeat count (from dpas_info) as template arguments. Host implementation will be changed in this PR. Device implementation will be changed later.

What are the list of failing tests per each configuration?
