Summary: Replace exception by setting valid_ = false in DBIter::MergeValuesNewToOld().

Test Plan:
Not sure if I am right at this, but it seems we currently don't have a good
way to test that code path as it requires dynamically set merge_operator = nullptr
at the time while Merge() is calling.

Adds counter for bytes moved (files pushed down a level rather than compacted) to compaction
IO stats as Moved(GB). From the output removed these infrequently used columns: RW-Amp, Rn(cnt), Rnp1(cnt),
Wnp1(cnt), Wnew(cnt).
Example old output:

Summary:
Introduces a new class for managing write buffer memory across column
families.  We supplement ColumnFamilyOptions::write_buffer_size with
ColumnFamilyOptions::write_buffer, a shared pointer to a WriteBuffer
instance that enforces memory limits before flushing out to disk.

Test Plan: Added SharedWriteBuffer unit test to db_test.cc
