Androidmk_suffix has been captured with "m vendor-snapshot". But the
suffix is to avoid collision with core variants, so the suffix should be
based on the existence of core variants. This change sets the suffix by
using OtherModuleDependencyVariantExists. This way we can also avoid
mutators and global states.

When using the directed vendor snapshot, the build fails because soong
fails to find some variants of the modules that have been excluded
from VENDOR_SNAPSHOT_MODULES, even though those modules are not going
to be used by the build.
The solution implemented here is to generate fake versions of those
modules (empty files) and include them in the generated Android.bp,
so that soong finds the modules, even though trying to use them would
fail.

A fake vendor snapshot is a vendor snapshot whose prebuilt binaries and
captured headers are all empty. It's much faster to be built than the
real vendor snapshot, so users can exploit the fake vendor snapshot to
reduce the size of vendor snapshot they need, by installing the fake

Rewriting LLNDK dependencies with .llndk suffix requries referencing
a global data structure to determine if a given library is an LLNDK
library and therefore needs the .llndk suffix. References to
global data structures from mutators must be removed to support
incremental Soong analysis. Instead, move the LLNDK stubs rules
into the vendor variant of the implementing cc_library so that
the original name can be used.
As an incremental step, the llndk_library modules are left in
place, and the properties are copied into the cc_library via
the dependency specified by the llndk_stub property. A followup
will move the LLNDK properties directly into the cc_library and
delete the llndk_library modules.
The global list of LLNDK libraries is kept for now as it is used
to generate the vndk.libraries.txt file.

Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly. Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module. Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.

The prebuilt-vs-source selection operates by setting SkipInstall on

When building a vendor snapshot, the general rule the
build system uses to select a module for inclusion into
the vendor snapshot is if it's a framework module.
However, there are cases where a partner may modify the
framework module, thereby assuming control of that
module.
This change adds the exclude_from_vendor_snapshot
property allowing the partner to mark a module that
would normally be included in the vendor snapshot for
exclusion. This module is then built from source when
building the vendor image against the vendor snapshot.

CFI modules can't link against non-CFI static libraries, and vice versa.
So without capturing both CFI and non-CFI static libraries, vendor
modules won't be able to use CFI, which will be a critical security
hole.
This captures both CFI and non-CFI variants of all static libraries for
vendor snapshot, except for those whose cfi are explicitly disabled.
For example, suppose that "libfoo" is defined as follows.
cc_library_static {
name: "libfoo",
vendor_available: true,
}
As it doesn't have cfi disabled, two libraries "libfoo.a" and
"libfoo.cfi.a" will be captured. When installed, vendor snapshot module
for "libfoo" will look like:
vendor_snapshot_static {
name: "libfoo",
src: "libfoo.a",
cfi: {
src: "libfoo.cfi.a",
},
}
The build system will recognize the "cfi" property, and will create both
CFI and non-CFI variant, allowing any modules to link against "libfoo"
safely, no matter whether CFI is enabled or not.
Two clarification:
1) The reason why we don't create separate modules is that DepsMutator
runs before sanitize mutators. CFI and non-CFI variant of a library
should exist in a single module.
2) We can't capture CFI variant if the source module explicitly disables
cfi variant by specifying the following.
sanitize: {
cfi: false,
}
In this case, only non-CFI variant will be created for the vendor
snapshot module.
