Improves tests for tagged schemes.

- Adds a file for tests for each individual tagged scheme and adds more
  tests for each type in
  ```tss-esapi/src/structures/tagged/schemes.rs```.

- Adds missing support for `Hmac` variant when using `signing_scheme`
  and `set_signing_scheme` methods.

- Changes name of variable holding the signing scheme.

- Refactors the tagged signature scheme tests.
