  Fix integer overflow in BlockLayoutEncoder
  
  BlockLayoutEncoder::mCurrentOffset's computation had the
  possibility of causing integer overflows in multiple places,
  so this CL adds CheckedNumeric variables in a number of
  these occurrences in order to prevent integer overflows and
  causing issues.
  
  The issue in this case was an integer overflow causing the
  code in ValidateTypeSizeLimitations.cpp to use an invalid
  result from "layoutEncoder.getCurrentOffset()", which ended
  up compiling a shader which would later cause an OOM error.
