using `windowsHide: true` is causing an issue on windows: Ctrl + C
handling isn't enabled and no `SIGINT` is sent to the child process when
users exit the process. See https://github.com/nodejs/node/issues/29837
and https://github.com/nodejs/node-v0.x-archive/issues/5054 for
reference. This will cause leftover processes throughout nx.
This PR sets `windowsHide: false` everywhere except for the plugin
workers and some short-lived utils. They `spawn` child processes but
have explicit handling to make sure they kill themselves when the parent
process dies, so the missing Ctrl + C handling doesn't cause issues.
We will follow up to make sure any other culprits that still cause
windows popups (especially when used through Nx Console) are handled.
Leaving no leftover processes running is more important for now, though.
Keep in mind the underlying tooling (like vite) might have some windows
popups themselves that Nx will inherit.

## Current Behavior
<!-- This is the behavior we have today -->
The package manager is detected based off of the relative `cwd` which in
most cases is `''`. This incorrectly goes off of the `cwd` of the
command rather than the location of the `package.json` file being
modified.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
The package manager is detected based off the absolute path of the
directory containing the `package.json` file being modified. So if this
is the root, it will detect the package manager at the root rather than
the `cwd`
