Add parentheses in FLATBUFFERS_MAX_BUFFER_SIZE, FLATBUFFERS_MAX_64_BUFFER_SIZE to avoid preprocessor definition collision (#8377)

Browse Source 
In case when flatbuffers are being used along with other project that defines "max" preprocessor macro, the ::max() in FLATBUFFERS_MAX_BUFFER_SIZE and FLATBUFFERS_MAX_64_BUFFER_SIZE is incorrectly being expanded to the macro. Adding parentheses enforces function-like interpretation.
