This code creates the representation of the enclave filesystem using FatFs - Generic FAT Filesystem module.
There are two separate artifacts generated: libfatfs_enclave.a is a C++ static archive library to be linked together
with other static libraries to form the shared object that represents the SGX enclave, libfatfs_host.a is a C++
static archive library to be linked together with other static libraries to form the shared object representing
the host C++ layer that communicates with the host Java/Kotlin layer through JNI.
