A macro for creating a new Object Property.

The macro accepts the following:

• properties!(libspa::format::FormatProperties::<key>, Id, <value>)
• properties!(libspa::format::FormatProperties::<key>, <type>, libspa::utils::<type>(<value>))
• properties!(libspa::format::FormatProperties::<key>, Choice, Enum, Id, <default>, <value>, …)
• properties!(libspa::format::FormatProperties::<key>, Choice, Enum, <type>, libspa::utils::<type>(<default>), libspa::utils::<type>(<value>), …)
• properties!(libspa::format::FormatProperties::<key>, Choice, Flags, <type>, libspa::utils::<type>(<default>), libspa::utils::<type>(<value>), …)
• properties!(libspa::format::FormatProperties::<key>, Choice, Step, <type>, libspa::utils::<type>(default), libspa::utils::<type>(min), libspa::utils::<type>(max), libspa::utils::<type>(step))
• properties!(libspa::format::FormatProperties::<key>, Choice, Range, <type>, libspa::utils::<type>(default), libspa::utils::<type>(min), libspa::utils::<type>(max))
