Add Archetype TypeInfo::type_name accessor

[smokku]

This adds an accessor to get the type name from Archetype.

I use this in ECS debugger when the Reflect is not available, to at least show the name of the Component type.

Hmm this breaks release builds for some reason (both on stable and nightly). I need to revert this. Can you reproduce this error on your machine?

This feels like a compiler bug. Debug vs release builds shouldn't handle this case differently. I also have no clue how to resolve this / disambiguate 😄

[smokku]

Same here. Works in --debug does not compile in --release.

I see two solutions. Rename the getter to .get_type_name() (I don't like get_ getters)
or just make the field pub (smells iffy too).

I'm just so confused. We use this pattern everywhere.

With a bit of help from rust-lang Discord I present you #985

Can you spot the difference? 😜

Haha it took me a second. You left the debug_assertions in this time? Why do we need that?

[smokku]

No, I removed the cfg this time. It caused the field to be missing in release builds.
With the field missing, the code that wants to access it does not compile. :-)

Lol apparently i had my tabs mixed up. Glad to hear the world still makes sense.
