Add get_umf_debug_info.sh to print saved strings

Add the `get_umf_debug_info.sh` script to print saved strings.
It can be used with any user binary:

$ scripts/get_umf_debug_info.sh ./build/test/umf_test-base
./build/test/umf_test-base does not contain magic strings of the UMF library.

$ scripts/get_umf_debug_info.sh ./build/test/umf_test-ipc
./build/test/umf_test-ipc is statically linked with the UMF library.
Strings in /mnt/wsl/files/repos/unified-memory-framework/build/test/umf_test-ipc:
@(#) Intel(R) UMF version: 0.10.0-git4.gbf701ee8

$ scripts/get_umf_debug_info.sh ./build/test/umf_test-c_api_disjoint_pool
./build/test/umf_test-c_api_disjoint_pool is dynamically linked with the UMF library \
(/mnt/wsl/files/repos/unified-memory-framework/build/lib/libumf.so.0.10.0).

$ scripts/get_umf_debug_info.sh ./build/lib/libumf.so
./build/lib/libumf.so is the UMF library (/mnt/wsl/files/repos/unified-memory-framework/build/lib/libumf.so.0.10.0).
