rust: replace most "operation" structs with functions

The hg-core crate has a partially-formed concept of "operation",
represented as structs with constructors and a `run` method.

Each struct’s contructor takes different parameters,
and each `run` has a different return type.
Constructors typically don’t do much more than store parameters
for `run` to access them.

There was a comment about adding an `Operation` trait
when the language supports expressing something so general,
but it’s hard to imagine how operations with such different APIs
could be used in a generic context.

This commit starts removing the concept of "operation",
since those are pretty much just functions.
