* Add some debug logging for timing in module compiles
This is sometimes helpful when debugging slow compiles from fuzz bugs or
similar.
* Fix total duration calculation to not double-count
Some platforms such as AArch64 Linux support different memory page
sizes, so we need to be conservative when choosing the code section
alignment (which is equal to the page size) by using the maximum.

This commit improves our small publish script for Wasmtime with the goal
of being able to run it on CI. This fixes a few issues with the current
script such as:
* If you rerun the script it won't try to republish crates already
published.
* Once a crate is published it won't print an error trying to re-add the
`wasmtime-publish` owner group.
* This will automatically retry publishing crates if they fail to get
published, hopefully handling issues like rate limiting and/or waiting
for the index to update.
The eventual goal is to run this script on a tag automatically on CI so
we don't have to do it manually, and these changes should make the
script more robust to run on CI and also makes it so we can inspect
failure outputs and rerun it locally.
For now these changes aren't heavily tested since it's somewhat
difficult to do so, so for now I figure we'll need to babysit the next
release or two with this script.
Module linking is otherwise covered by other fuzzers and by enabling
module linking it rejects more modules than necessary due to
restrictions on import strings.
This also paves the way for unifying TargetIsa and MachBackend, since now they map one to one. In theory the two traits could be merged, which would be nice to limit the number of total concepts. Also they have quite different responsibilities, so it might be fine to keep them separate.
Interestingly, this PR started as removing RegInfo from the TargetIsa trait since the adapter returned a dummy value there. From the fallout, noticed that all Display implementations didn't needed an ISA anymore (since these were only used to render ISA specific registers). Also the whole family of RegInfo / ValueLoc / RegUnit was exclusively used for the old backend, and these could be removed. Notably, some IR instructions needed to be removed, because they were using RegUnit too: this was the oddball of regfill / regmove / regspill / copy_special, which were IR instructions inserted by the old regalloc. Fare thee well!
