Auto merge of #126777 - Zalathar:normalize-colon, r=lcnr

Require a colon in `//@ normalize-*:` test headers

The previous parser for `//@ normalize-*` headers (before #126370) was so lax that it did not require `:` after the header name. As a result, the test suite contained a mix of with-colon and without-colon normalize headers, both numbering in the hundreds.

This PR updates the without-colon headers to add a colon (matching the style used by other headers), and then updates the parser to make the colon mandatory.

(Because the normalization parser only runs *after* the header system identifies a normalize header, this will detect and issue an error for relevant headers that lack the colon.)

Addresses one of the points of #126372.
