build-system: clean up TCG/TCI configury
Make CONFIG_TCG_INTERPRETER a Meson option, and enable TCI (though with a warning) if the host CPU is unsupported, making it more similar to other --enable-* options. Remove TCG-specific include paths from !CONFIG_TCG builds. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
