Git ignore *-build directories used by RunCMake tests
Currently after running CMake tests, git status
shows hundreds of files and directories to add.
We could limit it by excluding *-build/
directories.
I also changed RunCMake.Syntax
tests which generating tests, to produce output into EscapeChar-build/
directory.
As a result generated tests are excluded from Git by default (by EscapeChar-build/
directory)
