Uses SipHasher implementation added to the project. Ideally the output
would remain consistent between builds (though the worst case of an
updated algorithm would be a string lookup for cross-container reads
only).
Sort the flags first so everything is always added to the hasher in the
same order - note this code is only run at build time, not runtime.
Next step is to write this fingerprint into the package.map file and
introduce a flag to guard this change.

Now that we have Rust 1.80 LazyLock is available in the standard library
so we no longer need to use external crates such as lazy_static.

This commit changes java reader to directly read the flag value from the
map file instead of load the entire file.

This change implements SipHasher in rust and java to make sure same
bytes array will be hashed into the same u64.
The implementation is needed, thus when rust, and java code read the
same flag file, they can find the same entry based on the same key.

This change removes the local copy of the flag file in PackageTable, and
FlagValueList.
PackageTable copied the entire flag file into memory, and the
FlagValueList copied the entire flag value list into memory. In this
change FlagValueList directly access the flag value list in the memory.
PackageTable will iterate the file, and find the target package node.

"fake_device_config" and "strict_mode_stub" provide stubs and do not
contain any implementation details. Specifying the property
"is_stubs_module" to these modules allow inter-container dependency on
these modules.

Close file stream, since the in the restrict mode the runtime will check
whether all the resource is closed when it is out of scope.

This change changes the logic to read the flag value from new storage.
Before it check the existence of a file. Not it will directly check the
flag value from DeviceConfig.

This change adds code in java code to read from new storage. However the
generated code won't geneerate code contains code for new storage, since
the build system won't pass `allow-instrumentation` to java codegen.

but might avoid any accidental name drift/bugs in the future.

Marking the member as final for non-test scenarios allows for
optimizations that may otherwise be unavailable, and avoids ambiguity
about mutability.
