This adds a new soong module that transforms selinux policy files to
policy.conf file. It uses m4 macro with various variables, and replaces
transform-policy-to-conf macro in system/sepolicy/definitions.mk.

- policy cil files shipped to the device
- CTS tests that needs general_policy.conf

se_build_files module globs given srcs from sepolicy directories and
acts as a filegroup with the following tags, which can be used to build
system side policy files.
- plat
- plat_public
- system_ext
- system_ext_public
- product
- product_public
- reqd_mask
se_build_files module acts like the build_policy macro in Android.mk.
Normal genrule module can't easily handle that, because both file order
and directory order matter.
Support for vendor/odm is to be added in the future.
Bug: 33691272

For devices launching with Android Q or later, vendor_property_contexts
and odm_property_contexts should only contain vendor and odm properties.
This checks property_contexts files in build time.
To temporarily disable this check, users can set
BUILD_BROKEN_VENDOR_PROPERTY_NAMESPACE := true in BoardConfig.mk. But
VTS is still enforced, so users will have to fix the violations anyway.

As image variants are now supported directly by android.Module, this
removes a custom mutator in selinux_contexts and uses image variant

`product_sepolicy.cil` and `product_mapping_file` to

define macros.

This is caused by `secilc.c` trying to read the empty file:

sysprop type checker compares a sysprop_library API file and
property_contexts files, and detects if there are any mismatches of
property types. For example, the following snippets are detected.
// foo.sysprop
prop {
prop_name: "ro.foo.bar"
type: Integer
...
}
// property_contexts
ro.foo.bar u:object_r:foo_prop:s0 exact string
"ro.foo.bar" is an Integer in .sysprop file, but it's a string in
property_contexts file.

public/property_contexts needs to be included regardless of
API level so that the property *labels* are always included.
Else, devices without PRODUCT_COMPATIBLE_PROPERTY (shipping
API level <27) will run into denials because the props are
labeled `default_prop`.
As a side benefit, this reduces deviation in test matrices.
The guard was originally introduced in:
e49714542e "Whitelist exported platform properties"
Test: Build for device without PRODUCT_COMPATIBLE_PROPERTY,
no more denials for accessing `default_prop` from e.g. HALs.

This is to migrate sepolicy Makefiles into Soong. For the first part,
file_contexts, hwservice_contexts, property_contexts, and
service_contexts are migrated. Build-time tests for contexts files are
still in Makefile; they will also be done with Soong after porting the
module sepolicy.
The motivation of migrating is based on generating property_contexts
dynamically: if we were to amend contexts files at build time in the
future, it would be nicer to manage them in Soong. To do that, building
contexts files with Soong can be very helpful.

New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.
Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.
