Hello Atul, as far as I can tell VisIt 3.1.0 binary available from the VisIt downloads page (https://wci.llnl.gov/simulation/computer-codes/visit/executables) for Linux (Debian 9.0 64bit specifically) does have the plugin included.
To check you should see if there are files visit3_1_0.linux-x86_64/3.1.0/linux-x86_64/plugins/databases/libECarpetHDF5Database_ser.so visit3_1_0.linux-x86_64/3.1.0/linux-x86_64/plugins/databases/libECarpetHDF5Database_par.so visit3_1_0.linux-x86_64/3.1.0/linux-x86_64/plugins/databases/libICarpetHDF5Database.so visit3_1_0.linux-x86_64/3.1.0/linux-x86_64/plugins/databases/libMCarpetHDF5Database.so which are the compiled shared libraries (not the src files). I can confirm that that plugin can read in CarpetHDF5 files (did so today). This is for VisIt 3.1.0 git version 134a7fd (according to the about dialog). I would check that you have not disabled the CarpetHDF5 database plugin in the "Options/Plugin Manager" menu. Other than that I am not sure at all what could be happening. I have seem issues with HDF5 files being of too new a format (eg if ldd cactus_sim reports libhdf5.so.10 but "ls visit3_1_0.linux-x86_64/3.1.0/linux-x86_64/lib/libhdf5.so.*" is less than 10) but that does not (as far as I know) affect Cactus since we ask the newer libraries to write files readable by the old versions. Just for completeness' sake I am attaching a screenshot showing where CarpetHDF5 shows up for me.
