ispc: upgrade 1.19.0 -> 1.20.0

* Release Notes:
  https://github.com/ispc/ispc/releases/tag/v1.20.0

* Drop already merged patches:
  0001-CMakeLists.txt-allow-to-pick-llvm-config-from-usr-bi.patch
  0001-CMakeLists.txt-link-with-libclang-cpp-library-instea.patch
  ffc75e464ff2b8fce7dbf74f1846ebd0852bc6f9.patch

* Fix packaging to ensure libispcrt is packaged correctly.

* ISPC runtime with CPU support can either be enabled with OpenMP or
  TBB. TBB is enabled by default that needs meta-oe to be included.
