Ben Reeves 32cd9899c8 bevy_render: Add attributes and attributes_mut methods to Mesh. (#3927)
# Use Case

Seems generally useful, but specifically motivated by my work on the [`bevy_datasize`](https://github.com/BGR360/bevy_datasize) crate.

For that project, I'm implementing "heap size estimators" for all of the Bevy internal types. To do this accurately for `Mesh`, I need to get the lengths of all of the mesh's attribute vectors.

Currently, in order to accomplish this, I am doing the following:

* Checking all of the attributes that are mentioned in the `Mesh` class ([see here](0531ec2d02/src/builtins/render/mesh.rs (L46-L54)))

* Providing the user with an option to configure additional attributes to check ([see here](0531ec2d02/src/config.rs (L7-L21)))

This is both overly complicated and a bit wasteful (since I have to check every attribute name that I know about in case there are attributes set for it).
