Template tag codemod namehint

[void-mAlex]

builds upon the codemod ts branch to add optional naming hint different than babel-import-util transforms for us by default in the internal build of embroider
by default this will capitalise all words and concat any hyphens folder separators are replaced with _ to make it a valid js identifier

for now this would transform the known case of div helper to an import named Div and used as is in a strict mode template
initial testing suggests this works fine
{{Div}}

would love feedback if this is an acceptable approach to achieving this feature for the codemod
