Macro nih_plug::debug::nih_dbg

macro_rules! nih_dbg {
    () => { ... };
    ($val:expr $(,)?) => { ... };
    ($($val:expr),+ $(,)?) => { ... };
}

Analogues to the dbg!() macro, but respecting the NIH_LOG environment variable and with all of the same logging features as the other nih_*!() macros. Like the nih_debug_assert*!() macros, this is only shown when compiling in debug mode, but the macro will still return the value in non-debug modes.
