Add flag_table module for the creation of flag.map file. This is a hash
table in file similar to package.map hash table in file. This is created
per each container. It stores a mapping from a composite key (package id
and flag name) to its flag id (within package index of a flag).
This hash table allows us to look up the within package offset for a
specific flag. Along with the package offset obtained from package.map,
we will be able to find the global offset of a flag in the flag value
file.
Added unit tests to lock down the table creation and serialization.

merge storage_test_1_part_1.aconfig and storage_test_1_part_2.aconfig
into one aconfig file: storage_test_1.aconfig
remove two flags from test_1 package so the total number of flags across
three aconfig package is now 8, which is easier to test in unit test.

https://android-review.git.corp.google.com/q/topic:limit_systemsdk
introduced a new check for preventing the use of system SDKs above 34
from Java modules in the vendor partition.
As this may break some unprepared targets, introduce
BUILD_BROKEN_DONT_CHECK_SYSTEMSDK as a temporary escape hatch.
This flag will be deleted eventually.

Test: Add BUILD_BROKEN_DONT_CHECK_SYSTEMSDK := true to BoardConfig.mk

Previously, we checked if PRODUCT_SHIPPING_API_LEVEL >= 28, but that no
longer is needed because upgrading from 29 to 35 is not expected. All
devices running Android V are expected to be shipped after 28.
Furthermore, this fixes non-device targets (like sdk) where
PRODUCT_SHIPPING_API_LEVEL is unset.

Has the side effect of not polluting the local developer metrics with
benchmark runs too.

The "force_read_only" mode is designed for libraries shared among
multiple containers for the following two scenarios where:
1. The library must be built with read_only flags or
2. Different containers requires different values for the same flags.
In this mode, the library includes only non-exported flags, adhering to
the concept that exported flags should maintain consistent values across
containers. Additionally, regardless of their original permissions, all
flags within this mode will be set to read_only.

This change disallows Java modules in the vendor partition to use System
SDK that is newer than API level 34; 34 is the latest allowed.
Background 1: with Trunk Stable, the system/vendor interface is released
at Q2 whereas the system/app interface is released at Q3. In other
words, at Q2, the APIs which will be added to the system SDK at Q3 are
not available. Since the system/vendor interface (which is fronzen at
Q2) is what the modules in the vendor partition will be building
against, they can't and shouldn't use those new APIs that will be added
in the future (Q3). Using those APIs is risky because there's a chance
that those APIs get removed or changed between Q2 and Q3. For example,
2024 Q2 is technically still Android U, not Android V.
Background 2: The use of Java APIs in the vendor partition had many
issues. Most significantly, those "vendor" Java apps are categorized as
part of the system partition because all Java app processes require
access to platform internal libraries that are prohibited to vendor
processes. Furthermore, since the Project Treble, the vendor partition
was re-purposed to a partition to host SoC-dependent bits - usually
HALs. Implementing HALs in Java has never been officially supported and
has had many loop holes.
We'd like to use both background 1 and 2 as a chance to disallow any
Java code in the vendor partition. However, since there are already some
Java modules in the partition, we can't suddenly ban it. The deprecation
will be made gradually, and this CL is the start.
This CL implements the "Make" part of the restriction. The "Soong" part
will follow.
Note that LOCAL_SDK_VERSION := current or LOCAL_SDK_VERSION :=
system_current is automatically overridden into 34 or system_34. This is
to prevent sudden breakage of vendor modules that have been targetting
the latest (i.e. current) API level. They will however fail if they use
APIs newer than API level 34.

Allow Soong modules to generate their own module-info.json entries
by merging Soong's module-info.json file into the one generated in
Make.
Skip collecting unnecessary ALL_MODULES.$(my_register_name).*

handled by Soong via the LOCAL_SOONG_MODULE_INFO_JSON property.

Add a function to assign flag id for flags in a package. We first assert
that the flags should have been sorted by its name, then assign a u32 id
to each flag in order. Note this cl adds the function, it will be used
in later cls.
