edits to Twenty Sixteen only, grouping the letter-spacing and text-transform overrides

[sabernhardt]

moving font-weight, letter-spacing, line-height and text-transform to .wp-block-buttons

Twenty Twenty already had a report on #58024, so this ticket (and patch) can address custom letter-spacing in Twenty Sixteen.

Even with the overrides in 58609.diff/58609.1.diff and [55999], a font-weight option from the Appearance control or a custom line-height would have no effect. In the alternative patch, I tried moving some CSS properties to the Buttons block instead of on the links (similar to @nidhidhandhukiya's 58024.1.patch).
