CryptoPkg/Library/OpensslLib: Combine all performance optimized INFs

* Remove IA32/X64 specific INF files for performance
  optimized OpensslLib and combine into OpensslLibAccel.inf
  and OpensslLibFullAccel.inf.
* Remove use of PcdOpensslEcEnabled and let the platform
  select the EC feature by using either OpensslLibFull.inf
  or OpensslLibFullAccel.inf.
* With PcdOpensslEcEnabled removed, roll back style of opensslconf.h
  and remove  opensslconf_generated.h. Move the choice to disable
  EC/SM2 into OpensslLib INF files using OPENSSL_FLAGS define.
* Update OpensslLibContructor() API to be compatible with all
  FW phases by using types from Base.h and using RETURN_STATUS
  type and values instead of EFI_STATUS type and values.
* Add /wd4718 to VS2015x86 for IA32 and X64 to disable warning
  for recursive call with no side effects.  This is a false
  positive warning that is not produced with VS2017 or VS2019.
