// Returns an HTML template page that embeds a MIME handler for `mime_type`.
// `internal_id` is written into the element's `internalid` attribute so
// MimeHandlerStreamManager can match the stream to the frame once the
// initial about:blank navigation commits.
//
// When `use_oopif` is true, the page contains an iframe (for OOPIF-based
// handlers like PDF and generic MIME handlers). Otherwise it contains an
// embed element (for legacy GuestView-based handlers). When `is_oopif_pdf`
// is true, uses Chrome's PDF-specific embedder HTML. When `use_oopif` is
// true but `is_oopif_pdf` is false, uses the generic OOPIF template for
// third-party MIME handlers. Otherwise uses the legacy GuestView embed
// template with a background color derived from the plugin info registered
// for `resource_url`.
