Accept intrinsic namings into -spirv-allow-unknown-intrinsics (#912)

Previously, enabling the option would let all intrinsics through
the translator. From now on, the option can be configured so
that only specific intrinsic calls with the given prefix are
allowed, while those not matching the prefix will result in an
error as if no option was given.

The allowed intrinsic prefixes are fed into the option as a
comma-separated list, akin to `--spirv-ext`. The list can also
be left unspecified, which, as before, will accept all intrinsic
calls into SPIR-V.

One of the relevant use cases involves llvm.genx.* intrinsics,
which stem from SYCL ESIMD code, but can also mix with common LLVM
intrinsics that stem from regular SYCL code. It would be desirable
to allow ESIMD-specific intrinsics, but still error out on other
unknown ones, To better highlight this case, all ESIMD-specific
tests have been switched to passing an explicit prefix to the
CLI option.
