  Remove angle::ErrorStream helper
  
  Most uses of the helper either use just the code or a fixed string,
  which compiles to a few instructions. Using this helper adds 200+ bytes
  of assembly to each use, due to the unneeded instantiation of
  ostringstream which allocates a buffer etc. The combined effect of this
  CL on an Android perf build is ~12KB (0.2%) reduction in size.
  
  The cases where the message is actually formatted are converted to an
  explicit use of ostringstream. Removing the helper so that the new code
  is explicit about the intent to use ostringstream, or an alternative way
  to format the message.
  
  Discovered accidentally while looking into size reduction due to
  __builtin_unreachable()
  
  Semi-automated code change, risk of copy-paste mistakes should be
  minimal.
