In the User Timing L3 spec
(https://w3c.github.io/user-timing/#measure-method), the
performance.measure function can take an options dictionary as its
second argument. If a non-empty dictionary is passed but neither of the
'start' nor 'end' members is present, a TypeError must be thrown.
This change adds checks for this case and raises the appropriate errors.
WPT coverage is also extended to check that user agents raise TypeErrors
as specified.
