opencl-clang: move to a separate recipe

Since this is managed as a separate repository, build it as a separate
component instead of bundling with LLVM/clang.

+Subject: [PATCH] point to correct llvm-tblgen
+
+Let llvm-tblgen path be passed from recipe itself.
+
+Also since we're going to do the patching ourselves, no need to look for
+git through cmake.
+
+Upstream-Status: Inappropriate [OE specific]
