[naga] Remove unneeded PartialEq derivations.

Browse Source 
Remove `PartialEq` derivations from various Naga IR types on which
equality doesn't really make sense. In some cases, derive only in
`cfg(test)` builds, so tests can check for expected output.

In the GLSL front end, use `append` to add new constants, not
`fetch_or_append`, since the latter requires `PartialEq` yet GLSL
doesn't permit duplicate declarations anyway.
