Remove Screenshot and Bubble menu options.

Currently, these two menu options are not implemented and have no
function(i.e, they are not used for developer purposes like Select
currently is). This CL removes them so as to not be distracting.

Bug: 286550932
Test: Manual; confirm options are gone and pill heights are correct.
