[Release] Increase test-release.sh verbosity

[Release] Increase test-release.sh verbosity

`test-release.sh` is too silent in some cases:

- Only the build proper is run verbosely, but `check-all` is not.
- `lit` is run without `-v`, so in case of failures one cannot see what's
actually wrong.

This patch fixes both issues, running all `${MAKE}` invocations with
`$Verbose` (except for `${MAKE} install` where it would only add noise),
and running `lit` with `-v`.

Tested on `x86_64-pc-linux-gnu` and `arm64-apple-darwin21.6`.
