Use jsdoc/multiline-blocks instead of multiline-comment-style

Replace multiline-comment-style (starred-block), which also forces
multiline // comments into block comments, with jsdoc/multiline-blocks.
That rule only enforces starred JSDoc layout for /** blocks (no text on
the opening line) and leaves multiline // comments unchanged for
internal documentation.

Fix multiline JSDoc in Types.ts.

Fixes #5899
