[clang-format] Disable some text proto delimiters and functions for google style

Summary:
This disables some of the most commonly used text proto delimiters and functions
for google style until we resolve several style options for that style.
In particular, wheter there should be a space surrounding braces ``msg { sub { key : value } }``
and the extent of packing of submessages on a same line.
