STYLE: Update m_Quiet initialization for compiler-specific behavior

Refactor `m_Quiet` member variable initialization using preprocessor directives to accommodate `_COMPILER_VERSION == 730` condition, improving code maintainability and clarity.

The _COMPILER_VERSION == 730 conditional compilation was added in e1fdf51 on 2004-09-29, and likely
corresponds to MIPSpro version 7.3.0 compiler work-arounds.
