Previously, three seperate crates create their own test baseline which
are nearly identical. This is inconvinent when updating the baselines.
All three locations needs to be touched. This cl merges functions to
create test storage file base struct into aconfig_storage_file crate

1, add storage file type into storage files serialization
2, update aconfig_storage_read_api integration tests to not rely on
soong to produce read only storage files. Instead, have the test process
create temp read only storage file copies.

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.
