clang: split SPIRV-LLVM-Translator to its own recipe

The translator is not a part of the same source tree. As such it has
tendency to break on clang upgrades. Split it to its own recipe in order
to ease handling of clang.

This also makes it use SPIR-V headers provided by the spirv-headers
recipe instead of vendoring them in.

-Subject: [PATCH] SPIRV-LLVM-Translator: fix handling of built-in SPIRV targer
-
-If the SPIRV-LLVM-Translator is being built together with the LLVM, set
-the defines declaring whether SPIRV target is also included into the
-LLVM library or not. Otherwise llvm-spirv execution fails because
-spirv-ext option is registered twice.

-Subject: [PATCH] SPIRV-LLVM-Translator: build shared library
-
-By default SPIRV-LLVM-Translator builds only a static version of the library.
-Unfortunately this might result in linking erros when uninative is in play, if
-libLLVMSPIRV uses symbols which are provided only by the uninative libc and are
-not provided by the host libc.
