Michael D Kinney deee46d276 CryptoPkg/Library/OpensslLib: Fix CLANG compatibility issues ...

Update the CryptoPkg to support CLANGPDB and CLANGDWARF from
both Windows and Linux host environments.

* Add PcdOpensslLibAssemblySourceStyleNasm to select the correct
  optimized assembly source style for OpensslLib for IA32/X64.
  NASM style is for MSFT and CLANGPDB. GAS style is for GCC.
  Use this PCD in OpensslLibAccel.inf and OpensslLibFullAccel.inf
  to select between .nasm and .S files.
* Add intrinsic functions required by CLANG IA32/X64 builds.
  * __ashlti3
  * __lshrdi3
* Disable warning -Wno-error=unused-function for CLANG build
  compatibility
* Set -D OPENSSL_NO_INLINE_ASM for CLANG build compatibility
* Update TestBaseCryptLib to split out the implementation of
  main() into its own C file that is only use for host-based
  unit tests. This is due to CLANGPDB for host environments
  injecting a __main() call that can only be resolved in host
  based builds that link against host libraries.
* Update Configure.py to update IA32/X64 [Sources] sections
  with feature flag expressions using the new PCD
  PcdOpensslLibAssemblySourceStyleNasm.
