simplemerge: convert MergeInput to regular, non-attr.ib class
I'm about to add more logic and state to it.

simplemerge: replace `**opts` passed to `simplemerge()` by keyword arguments
The `simplemerge` module is library code; it should not get an
unmodified `opts` dict from the `simplemerge` extension.

automation: use gp3 volume type
This is a newer volume type. It offers a better baseline of performance
by default and is ~10% cheaper. It doesn't offer burst credits. But
its performance is guaranteed, unlike gp2, which had wonky performance
behavior.

automation: use m6i instances
This instance type is much, much faster than t3 and can perform
tasks much quicker.

narrow: add support for merging add and remove outside of the tracked set
This extend
f1eb77dceb36 to test and support the remaining action. Or, at least,
the simple incarnation of them.

status: prefer relative paths in Rust code
… when the repository root is under the current directory,
so the kernel needs to traverse fewer directory in every call
to `read_dir` or `symlink_metadata`.
Better yet would be to use libc functions like `openat` and `fstatat`
to remove such repeated traversals entirely, but the standard library
does not provide APIs based on those.
Maybe with a crate like https://crates.io/crates/openat instead?
Benchmarks of `rhg status` show that this patch is neutral in some configurations,
and makes the command up to ~20% faster in others.
Below is semi-arbitrary subset of results. The four numeric columns are:
time (in seconds) with this changeset’s parent, time with this changeset,
time difference (negative is better), time ratio (less than 1 is better).
