Always specify version to use aidl_interface except it is unstable

As-is, the rule for versions of generated modules from aidl_interface is
implicit and messy. For example, the version that <aidl_interface>-cpp
stands for can be different depending on the context(it can be the
latest stable version n or unstable version). And the version
<aidl_interface>-unstable-* or <aidl_interface>-* refers to can be
changed in accordance with freezing the interface. And also, for native
modules, version name and generated library file name is sometimes
mismatched.

So, I make it more explicit. There are only two rules
1. If an interface is unstable, the generated module name is
<aidl_interface>-<backend>

2. If not, the generated module name is always
<aidl_interface>-V<version>-<backend> (the version for ToT version is
the latest version + 1)

And the library name(so, jar, and so on) is the same as the generated
module name.

In terms of implemenation, the logic around version is getting simpler.
And Java, C++, NDK module creation logic is moved to PreArchMutator
because the other aidl_interface's version infomation is unknown
in the LoadHook phase, so we cannot find proper imported library name
which includes the version

Note that AIDL still generates <aidl_interface>-<backend> and
<aidl_interface>-unstable-<backend> to prevent unexpected breakage in
downstream branch and apply the change gradually, but it will be done
before release.
