Add utouch command from uutils/coreutils

[ysthakur]

Part of #11549

Description

This PR adds a utouch command that uses the touch command from https://github.com/uutils/coreutils. Eventually, utouch may be able to replace touch.

The conflicts in Cargo.lock and Cargo.toml are because I'm using the uutils/coreutils main rather than the latest release, since the changes that expose uu_touch's internal functionality aren't available in the latest release.

User-Facing Changes

Users will have access to a new utouch command with the following flags:

@ysthakur What's the latest here?

[ysthakur]

@fdncred Sorry, I've been really busy and haven't touched this for a week. The uutils side is currently not ready but I think I know what to do, and I'll be updating that today or tomorrow. Hopefully we can get that one merged by the end of the week

[fdncred]

Thanks for the heads-up @ysthakur. I appreciate your efforts here.

[fdncred]

How's this going? Are we waiting for changes to land at coreutils?

[ysthakur]

@fdncred Yeah, I just pinged Terts. Here's the PR, forgot to link it before: uutils/coreutils#5946.

[fdncred]

@ysthakur Is there any hope to getting the coreutils PR landed?

[ysthakur]

@fdncred Yes, sorry I've left it alone for a while. I wasn't quite sure how to interpret Terts's suggestions, but I just pushed a commit and will be bothering him about it :)

[fdncred]

ok, thanks for the update. appreciate your help.

[fdncred]

time for my check in again. what's the status here?

[ysthakur]

@fdncred Currently waiting on a review for the PR I made in uutils/coreutils.

[fdncred]

@ysthakur wow! the uutils pr landed. we can finally progress on this one. yipee!

[ysthakur]

I think touch is accidentally added to the default shell context twice, once with the filesystem commands and once with the format commands. I only added UTouch once there, with the filesystem commands.

Edit: Fixed in #13371.

[fdncred]

good catch. I don't think it should be the formats section.

[ysthakur]

By the way, this PR isn't dead, it's just that there's a bug in the way uutils parses dates (uutils/coreutils#6629). I think I've found the cause, more or less, and am working on a fix there.

Thanks for the update yash. Sorry this is such a hassle.
