meson: build clover

This has only been compile tested.

v2: - Have a single option for opencl (Eric E)
    - fix typo "tgis" -> "tgsi" (Curro)
    - Don't add "lib" to pipe loader libraries, which matches the
      autotools behavior
v3: - Remove trailing whitespace
    - Make PIPE_SEARCH_DIR an absolute path
v4: - add trailing / to LIBCLC defines
