glob command supports more metacharacters than filesystem commands like cp and mv #10498
Description
Describe the bug
It looks like only the glob command supports the the csh-style `{}' metacharacters, the file utilities do not.
You could argue this is more of an enhancement request, but I think globbing is so fundamental a shell experience that it must be consistent across use cases.
How to reproduce
> touch a.foo a.bar
> ls
╭───┬───────┬──────┬──────┬──────────╮
│ # │ name │ type │ size │ modified │
├───┼───────┼──────┼──────┼──────────┤
│ 0 │ a.bar │ file │ 0 B │ now │
│ 1 │ a.foo │ file │ 0 B │ now │
╰───┴───────┴──────┴──────┴──────────╯
> glob a.{foo,bar}
╭───┬────────────────────────────────────╮
│ 0 │ /home/bobhy/src/rust/work/r3/a.bar │
│ 1 │ /home/bobhy/src/rust/work/r3/a.foo │
╰───┴────────────────────────────────────╯
So glob supports {}. Great!
> mkdir dir_a
> cp a.{foo,bar} dir_a
Error: × No matches found
╭─[entry #187:1:1]
1 │ cp a.{foo,bar} dir_a
· ─────┬─────
· ╰── no matches found
╰────
> ucp a.{foo,bar} dir_a
Error: nu::shell::file_not_found
× File not found
╭─[entry #188:1:1]
1 │ ucp a.{foo,bar} dir_a
· ─────┬─────
· ╰── file not found
╰────
cp and ucp do not. Not shown here, but neither do rm, mv, touch .
Expected behavior
I'd really like all Nu globbing to support '{}' metacharacters.

Additional context
Looking at the code, the filesystem utilities use crates/nu-glob, but glob uses wax::Glob.
Understood, I could do:
glob a.{foo,bar} | each {|p| cp $p dir_a}
with a minor loss of efficiency. But that's just papering over the crack...
