Harden CordRepBtreeReader against reading up to or beyond EOF
This change hardens the reader to Next() calls on EOF situations. It changes the 'consumed()' property inside CordRepBtreeReader into a 'remaining()' property which is easier to understand and use than the 'consumed()' property QED the function documentation and use in cord.cc
This change also adds the CharIterator test to the CordTest fixture enabling them to be run with btree cords.

Add AdvanceAndRead() test addressing the edge case surfaced in b/197776822
This adds a test explicitly exercising all possible AdvanceAndRead() calls on CharIterator. As per the linked bug, a partial or full small read ending exactly at the end of the last edge of a btree cord results in an attempt to read beyond that last edge and subsequent failure. We will fix the bug and enable these tests for btree in a subsequent change.
