Text input component issues

[danielelder]

The govTextInput component has the following issues:

• The label has to be either a H1, H2 or H3, there is no support for a non-heading "standard" label.
• The label has a hardcoded ID to link it to the input element, this would restrict the page to only being able to contain a single input box.
• The hint text and error message should be referenced by the select element using aria-describedby.
• Hard coded "error:" prefix does not allow for language translations.
• The prefix and suffix should contain the aria-hidden attribute to prevent them from being read out by screen readers.
• Input has the character count component built in but this isn't really recommended, it's only really suitable for use on the textarea input.

Observation: The hint text has the property lwc:dom="manual" that isn't used on other components, is this required?
