Should close#8616.
Related to #8590.
# Description
With the new builtin `match` command introduced in the `rust` source in
#8590, there is no need to have a custom `match` in the standard
library.
This PR removes the `match` command from `std.nu` and the associated
test.
# User-Facing Changes
Users can not access `match` from `std.nu`.
# Tests + Formatting
```
nu crates/nu-utils/standard_library/tests.nu --path crates/nu-utils/standard_library/ out+err> /dev/null; ($env.LAST_EXIT_CODE == 0)
```
gives `true`
# After Submitting

# Description
as closures now need to have explicit parameters, this PR adds the empty
`||` to the two closure of the `std match` test.

# Description
Was original asked here:
https://github.com/nushell/nushell/pull/8405#issuecomment-1465062652
Make it easier to extend standard library with submodules.
(For a new submodule called `xx.nu` the tests can be written in
`test_xx.nu`).
Test discovery is implemented.
# User-Facing Changes
There are no user-facing changes.
