This fixes a discrepancy between Make and Soong build systems.
Memtag sanitizers rely on the linker to mark the executable as
requesting heap/stack/globals tagging.

How it works:
1. build/make/core/Makefile generates a txt file with the kernel
version, which is taken from an explicit BOARD_KERNEL_VERSION value,
or extracted from the kernel image on the source tree, or extracted
from the kernel image extracted from the prebuilt boot.img.
The file is saved at
$ANDROID_PRODUCT_OUT/obj/PACKAGING/check_vintf_all_intermediates/kernel_version.txt.
2. If PRODUCT_ENABLE_UFFD_GC is "default", meaning the GC type needs to
be determined by the kernel version, build/make/core/Makefile copies
kernel_version.txt to
out/soong/dexpreopt/kernel_version_for_uffd_gc.txt.
3. build/soong/dexpreopt/config.go writes the the UFFD GC flag to
out/soong/dexpreopt/uffd_gc_flag.txt. The flag is determined by an
explicit PRODUCT_ENABLE_UFFD_GC value or by contruct_uffd_gc_flag.py,
which reads kernel_version_for_uffd_gc.txt and determines the flag
accordingly.
4. dex2oat takes the UFFD GC flag from uffd_gc_flag.txt.
5. post_process_props.py mangles ro.dalvik.vm.enable_uffd_gc based on
the same logic.

Test: Build with `OVERRIDE_ENABLE_UFFD_GC=default m` for device with no
UFFD support -
1. Check the existence of `-Xgc:CMC` in
out/soong/dexpreopt_arm64/dex_bootjars/android/system/framework/arm64/boot.invocation
(dex2oat invocation for a boot image)
2. Check the existence of `-Xgc:CMC` in
out/soong/.intermediates/packages/apps/Settings/Settings/android_common/dexpreopt/Settings/oat/arm64/package.invocation
(dex2oat invocation for an app defined in .bp)
3. Check the existence of `-Xgc:CMC` in
$ANDROID_PRODUCT_OUT/obj/APPS/Dialer_intermediates/oat/arm64/package.invocation
(dex2oat invocation for an app defined in .mk)
4. Check the value of ro.dalvik.vm.enable_uffd_gc in
$ANDROID_PRODUCT_OUT/product/etc/build.prop
Test: Build with `OVERRIDE_ENABLE_UFFD_GC=default m` for device with
UFFD support, and do the steps above.
Test: Build with `OVERRIDE_ENABLE_UFFD_GC=true m`, and do the steps
above.
Test: Build with `OVERRIDE_ENABLE_UFFD_GC=false m`, and do the steps
above.

Minor change to mapped_file module, create utility function to verify
file is readonly and map. Also, update the unit test to create temp pb
file instead of writing to the test dir.

This module is repsonsible for finding the storage file location based on a
pb file and then map these storage files into memory using memmap2
crate. The mapped files are cached in a static hashmap in this module.
Note that memmap2 crate has not been introduced to AOSP yet as a 3p
crate. It is in the process of importing to AOSP ATM. So in src/lib.rs,
we only include this module if we are building the target using cargo.
Also, the test storage files: package.map, flag.map and flag.val are
generated based on the storage test aconfig files in
aconfig/aconfig/tests dir. With aconfig create-cache command first to
produce cache files, and then aconfig create-storage command to create
each storage file.
aconfig create-cache --package com.android.aconfig.storage.test_1 --container system --declarations ./storage_test_1.aconfig --cache com.android.aconfig.storage.test_1.cache
aconfig create-cache --package com.android.aconfig.storage.test_2 --container system --declarations ./storage_test_2.aconfig --cache com.android.aconfig.storage.test_2.cache

This should be used to declare that a release config is an alias for
another one. Aliases have no release config files of their own, and are
primarily used to simplify continuous integration as releases happen.
