This commit adds test cases for Decomp_gzip.
A compressed data segment has been pre-set, configure GSDMA and decomp_gzip.
Compare the decompressed data with the original data
Run this qtest:
$ mkdir build && cd build && ../configure --target-list="riscv64-softmmu"
$ QTEST_QEMU_BINARY=./qemu-system-riscv64
