[Feature] Add `textStyles` field to CosmosTeme

[andrzejchm]

We need to be able to specify typography inside cosmosTheme for the ui components to use in accordance to designs:

• add CosmosTextStyleData textStyles to CosmosTheme simmilar to colors property.
• deprecate the CosmosTextTheme and values there should be now specified as properties of the CosmosTextStyleData class
