Add Ubuntu 20.04 support (#3625)

* Fix build warnings and errors for Ubuntu version 20.04

- Apply macro fix for GTEST_DISALLOW_ASSIGN_ and GTEST_DISALLOW_COPY_AND_ASSIGN_ from googletest project
- Fix usage of deprecated functions in openssl 1.1.0
- Include deprecated `sysctl.h` only in QNX build
- Fix warnings in InterfaceGenerator scripts

* Add 20.04 to supported platforms

* Remove broken tests after openssl1.1 update
