Eliza Weisman ea7178b8c6 trace-core: Add slightly more useful debug impls (#1014) ...

This branch improves the `fmt::Debug` implementation for `Metadata`,
and adds `fmt::Display` implementations for `FieldSet` and `ValueSet`.

When formatting a `Metadata`, only present fields are formatted --- if
optional fields, such as the file, line number, and module path are
`None`, they will be excluded. In addition, `Metadata` now formats its
`FieldSet` using `FieldSet`'s `fmt::Display` implementation, which is a
bit less noisy. Finally, the `Debug` output for `Metadata` now includes
the callsite that the metadata originates from.

The intention behind these changes is to make the output from failed
tests somewhat easier to interpret.
