fungible conformance tests: Inspect and Mutate (#13852)

* typo * - create test files for each fungile trait - begin implementing tests for the Inspect trait * wrap inspect tests in a macro * first run of mutate tests * move test implementation out of ballances * make tests more generic * transfer tests * combine inspect and mutate tests * set balance failing tests * can_deposit tests * can_withdraw tests * test reducible_balance * remove balanced stub * revert set_balance return val fix * typo * macro and dust trap tests * disable test when it doesn't make sense * remove debug comment * reduce macro boilerplate * improved var naming * improve variable naming * remove redundant comment * remove placeholder tests * remove placeholder tests * simplify macro * Update frame/balances/src/tests/fungible_conformance_tests.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * use Balance from T * fix copyright * add test doc comments * improve test naming * clippy * fix rustdoc errors * fix rustdoc * improve macro * improve variable naming * remove redundant comment * use path --------- Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com>
