added a new function called list_flag_with_info to list all the flags
given all four storage files (package.map, flag.map, flag.val, flag.info).
also exported this api thru cxx interface so aconfigd can use it.

1, add a new field in storage metadata proto, for each container, there
is a local override file.
2, update write api to expose the api to map a writable file given the
specific path. the cannonical api will require a storage metadata proto,
and then find the right file path and map it.
3, minor update to make the proto lib cc_library instead of
cc_library_static

rust_ffi_static right now will export excessive symbols, this lead to a
duplication of symbols when aconfig links against both
libaconfig_storage_file_cc and libaconfig_storage_read_api_cc. This is
because aconfig_storage_read_api crate depends on aconfig_storage_file
crate. To solve this problem, move create flag info file api to
aconfig_storage_write_api crate which is parallel to
aconfig_storage_read_api crate.

We need the aconfig APIs to be available on every mainline module, so
set the min_sdk_version as low as possible.

To help debug storage files. We need a binary to parse the storage
binary files and print out the flag values like device_config list
command. In addition, aconfig_storage_file needs to provide a public api
to allow flag cli to call to get the flag values. Therefore creating
this change.
This change includes the following changes:
1, Implement debug print trait for package table, flag table, and flag
value struct. So the debug dump is more readable.
2, Add a list flag api to create a vector of flag name and value tuples
given the storage file names. This api will be used by
aconfig_storage_file binary as well as aconfig flag cli.
3, Add a main.rs to create aconfig_storage_file binary to debug print
storage files or list all the flags in storage files. It has two
subcommands.
3.1 print command:
aconfig_storage_file print --file <storage file> --type
<package_map|flag_map|flag_val>
This command produce a debug print of a single the storage file content
3.2 list command:
aconfig_storage_file list --package_map <package map file> --flag_map
<flag map file> --flag_val <flag value file>
This command parses all storage files to print out list of flag values
in the following form:
<package>/<flag>, <value>
...
<package>/<flag>, <value>

Test: manual test of the binary command

Current aconfig_storage_file crate contains two things: 1,
aconfig storage file definition (which is used by aconfig crate for
storage file creation) and 2, flag storage file read api. With this
change, we are splitting 2 into its own crate aconfig_storage_read_api
In the long run, there will be 3 crates for aconfig_storage
1, aconfig_storage_file
It contains aconfig storage file definition, as well as a binary to help
print/dump aconfig storage binary files into some readable format.
2, aconfig_storage_read_api
This crate contains flag read apis. This crate depends on
aconfig_storge_file crate. This crate will be used by codegen.
3, aconfig_storage_write_api
This crate contains flag write apis. This crate depends on
aconfig_storage_file crate. This crate will only be used by aconfig
daemon to update flag values.

A more systematic fix. Now for each test point, we create temp file
copies at temp dir and explicitly set the file permission of these temp
files. This should bypass the issue that test build artifact file
permission are not guaranteed. Because we will generate these test
storage files on the fly at run time.

Using cxx to generate c++ code for the apis that are marked to exported
in the ffi mod in src/lib.rs. For generated code simplicity, it returns
a new flag struct for each rust api.
Create a cc_library to wrap around generated c++ code. See the created
aconfig_storage.hpp for the exported header. Note there is a nested
aconfig_storage::test_only_api namespace, where we place test only apis.
The production apis are placed under aconfig_storage namespace.

1, update android build soong targets as now libmemmap2 has been
introduced to android code base.
2, add three public apis for package offset query, flag offset query,
and flag value query. These apis assume the stoarge location pb file is
at /metadata/aconfig/aconfig_storage.pb. This file will be created by
storage daemon. For testing purposes, we also expose impl version of
these apis that accept a custom storage location pb file.

file is readonly and map. Also, update the unit test to create temp pb

Introduce a new proto to capture storage file location for each
container. This proto file will appeara as
/metadata/aconfig/storage_file_location.pb. Storage service daemon is
responsible for writing entires to it when a new storage file set is
available. The flag read lib will use this file to find the
corresponding storage file and mmap them.

lib will need it as well. The new crate is placed under
aconfig_storage_file dir.
