Fix argument ordering
Expected argument ordering should be:
1. Arguments listed in `args`.
2. Legacy/built-in features.
3. User-defined features.
Due to some implementation changes, user-defined arguments were being applied last, reducing the ability for features to properly toggle behaviors dynamically.
This also fixes an issue caught by this change where cc_sysroot was applying flags to actions that had no associated action config.

It's possible for there to be some arguments that are naturally
associated with the sysroot flag, for example on macOS there are
associated framework search paths that should be added with
`-F{sysroot}/Library/Frameworks`. There are also warnings flags you
might want to add such as `-Werror=missing-sysroot`. In this case I
think it's nicer to provide them alongside the sysroot definition,
instead of having to create a custom cc_args for them.

Consolidate action labels in toolchain args
Consolidates action labels used by re-implementation of legacy features to use logical groups rather than individually listing every action. This simplifies the rule definitions slightly.

Fix rule-based implementation of runtime_library_search_directories
As runtime_library_search_directories was written and reorganized through review, some instances of `$ORIGIN` were unintentionally renamed to `$EXEC_ORIGIN`. This change fixes those instances to correctly mirror CppActionConfigs.java.

BEGIN_PUBLIC
Implement archiver_flags as cc_args
This is the first change in a series that will reimplement the legacy
features defined in Bazel's Java code using the new toolchain rules. These implementations are redefined as raw arguments using the new toolchain rules, which allows for the definition shared and reused across different contexts.
This first change implements archiver_flags, which is used to produce the arguments for the archiver tool used by `cc_library`.
This CL also adds a test that compares the feature implementation produced by
the new rules to the feature implementation defined in Bazel's Java
code. This should make it easier to review the final result and ensure it
is functionally equivalent to the Java implementation.

Fix action label evaluation in cc_sysroot
Explicitly converts action labels in cc_sysroot to Label objects to address issues where the labels were being evaluated as relative to the module instantiating cc_sysroot rules.

Replace sysroot with a cc_sysroot macro.
This is part of what amontanez@ and I discussed about making C++ toolchains less "magic".
I'd like to do the same for cxx_builtin_include_directories, but that will require significantly more effort.
