Initial build configuration for Haiku (#86303)

* Haiku: Initial configuration support

Initially recognize Haiku as a supported platform in
Directory.Build.props and all scripts in eng/**.

* Drop some unused configure values

Drop some unused configure values from tryrun.cmake,
configure.cmake and config.h.in.

* Simplify error message in build.sh

Simplified an error message for the `--os` option to avoid maintaining a duplicate list of OSes.
