This adds a new method to either move the `gh` formula to the front
of the formula list to be installed or checks that the `gh` formula
is already installed some other way.
The `Homebrew::CLI::NamedArgs` class often returns frozen arrays so this one cannot
be easily modified in-place here. We just overwrite it instead.
I also updated the `brew reinstall` command logic to match for consistency.
```console
$ brew upgrade gh --verbose --debug

Source builds that use Git checkouts with submodules can choke when the
process UID does not match its EUID.
We can fix this by using the `reset_uid` option added in #17782.

This is primarily intended to resolve the `uninitialized constant
Utils::Backtrace` error in `formula_versions.rb:60` but I expanded it
to try to cover all existing usage of `Utils::Backtrace`.
I've followed the existing pattern, where `utils/backtrace` is
required in the context of where it's used. Many of these cases use
`Backtrace` in a conditional manner, so I've tried to ensure that the
`require` follows suit.
