Add CI check to ensure all TextViews have a style check

[BenHenning]

Related issue: #3971. We need to make sure that TextViews have a centrally managed style set so that RTL/LTR settings can be properly managed. To do this, we need a CI check that runs a script which parses all layout files to ensure that TextView elements have a style set that corresponds to a local codebase style (i.e. uses @style/).

For reference, I suggest looking at the manifest transformation script since it parses & modifies XML today (so it's a good basis for the parsing needs of this new TextView script).
