Do not project for windows runtime during read.

A type will not be fully initialized during read, so don't attempt to
project for Windows runtime until after all of the metadata reading is
correct.

If a type reading for a module is no completed, a call to
BinaryRangeSearch in MetadataSystem can fail, because some of the
entries in the types array will still be null.
