Correct modifier isConst initialization (#6645)

The previous implementation had two issues in the modifier processing loop:
1. isConst was incorrectly initialized to true, making the const check redundant
2. Premature loop break could skip processing important modifiers. e.g.
   isExtern

Changes:
- Initialize isConst to false by default
- Remove early break condition to process all modifiers

Fixes: #6606
