Replace serde/strum renames with rename_all

Instead of applying a `#[serde(rename = "foo")]` or `#[strum(serialize =
"foo")]` to each field of a struct or variants of an enum, apply the
appropriate `#[serde(rename_all = "style")]` or `#[strum(serialize_all =
"style")]` to the struct/enum.

In addition, in the places where the `lowercase` style is used and all
the fields/variants are a single word, replace that with `snake_case`,
since that seems to be the default everywhere with multi-word
fields/variants.
