Add Number Normalisation for SpeechT5 (#25447)

* add: NumberNormalizer works for integers, floats, common currencies, negative numbers and percentages

* fix: renamed number normalizer class and added normalization to SpeechT5Processor

* fix: restyled with black and ruff, should pass code quality tests

* fix: moved normalization to tokenizer and other small changes to normalizer

* add: test for normalization and changed the existing full tokenizer test

* fix: tokenization tests now pass, made changes to existing tokenization where normalization is covered; added normalize arg to func signature

* fix: changed default normalize setting to False, modified the tests a bit

* fix: added support for comma separated numbers, tokenization on the fly with kwargs and normalizer getter setter funcs
