vala: Implement valac.find_library Move CCompiler.compile to Compiler.compile so that ValaCompiler can use it. Also rewrite ValaCompiler.sanity_check to use it since it does a simple compile check. At the same time, it enhances ExternalLibrary to support arguments for languages other than C-like. Includes a test for this that links against zlib through Vala.
