data types TEXT, CHAR, VARCHAR, FLOAT and DOUBLE are not yet supported by vectorized path
This patch introduces an example for Google benchmarking suite to measure a perf diff
b/w legacy scan/filtering code and the templated version
* Adds CompressInterfaceLZ4 which uses LZ4 API for compress/uncompress.
* Adds CMake machinery to search LZ4 on running host.
* All methods which use static data and do not modify any internal data - become `static`,
so we can use them without creation of the specific object. This is possible, because
the header specification has not been modified. We still use 2 sections in header, first
one with file meta data, the second one with pointers for compressed chunks.
* Methods `compress`, `uncompress`, `maxCompressedSize`, `getUncompressedSize` - become
pure virtual, so we can override them for the other compression algos.
* Adds method `getChunkMagicNumber`, so we can verify chunk magic number
for each compression algo.
* Renames "s/IDBCompressInterface/CompressInterface/g" according to requirement.

Fix build errors
Update logic to debug
There is a suspicious write engine method updateColumnRecs which
receives a vector of column types but does not iterate over them
(otherwise it will be identical to updateColumnRec in logic).
Other than that, the updateColumnRec looks like the center of all
updates - deleteRow calls it, for example, dml processor also calls it.

Descriptive vector emptines check
There are multiple overloaded version of the low level DML write methods to
push down CSC column type. WE needs the type to convert values correctly.
Replaced WE_INT128 with CSC data type that is more informative.
Removed commented and obsolete code.
Replaced switch-case blocks with oneliners.
When the API inserts data into ColumnStore which will roll over into a
new extent that data wasn't being put into the new extent and corruption
occured. This patch now tracks the additional data and inserts it into
the new extent. It also makes sure the LBIDs are stored so that they are
correctly committed.
