[indic-generator] Remove three unneeded Myanmar overrides U+AA74-6 

These three characters have Indic_Syllabic_Category=Consonant_Placeholder. The
original evidence that prompted these overrides says they can take tone marks.
They are not subjoined: Khamti Shan apparently does not use subjoined
characters at all. Therefore, PLACEHOLDER is good enough and these need not be
overridden to C.
