Update toolchain variable definitions to allow static linking
Updates the rules-based-toolchain variable definitions to reflect the how the variables are used in Bazel's CppActionConfigs.java Java implementation, particularly with respect to static linking.

BEGIN_PUBLIC
Makes the `args` attribute of `cc_feature` optional so that users may declare sentinel features that do not have any inherent arguments.

BEGIN_PUBLIC
Remove the "data" attribute from cc_action_type_config.
Technically speaking, data shouldn't be associated with action types. Instead, data should be associated with either a tool or a set of flags.
For example, instead of the cc_compile action having the header files as a data dependency, the "include_paths" cc_arg should instead declare `data = <header files>`.
This will allow us to, once we have a fully starlark-ified c++ toolchain, do much finer-grained dependencies. This will allow us to, for example, not provide header files to the action when the user enables the feature "nostdlib".

BEGIN_PUBLIC
Remove legacy toolchain flags.
This will allow us to enforce that users of the rule based toolchain are not using legacy toolchain resolution, and simplify toolchain creation.

Change-Id: I6ea4fad8ddf1a06ad17d706d82e54eb7f05aa6c6
BEGIN_PUBLIC
Create a cc_directory_tool rule.
This should allow for easy definition of tools from the sysroot. For example:
cc_directory_tool(
name = "clang",
directory = "@sysroot//:sysroot",
executable = "usr/bin/clang",
)

You now refer to this instead of a string containing the repo mapped path.

BEGIN_PUBLIC
Doing a transition to the exec platform in rule-based toolchains was causing unusual behaviors when attempting to restrict compatibility. This changes most of the toolchain rules to be evaluated from the target platform configuration, only transitioning to the exec configuration when explicitly requested.

Change-Id: I8716b9a517d9f3be306cdf96dafb98a868a3f83b
BEGIN_PUBLIC
In create_cc_toolchain_config_info, the target_system_name, target_cpu, and target_libc attributes are documented as required and deprecated. In practice, these may safely be `None`. This updates the cc_toolchain rule implementation to no longer require that these attributes are set to arbitrary values.

BEGIN_PUBLIC
Fix the load broken by a new version of buildifier.
Apparently the native-cc lint has been split into native-cc and native-cc-proto. This meant that our native.cc_proto_library was getting incorrectly turned into cc_proto_library when copybara invoked buildifier.

BEGIN_PUBLIC
Refactor action sets for consistency and simplicity
* Remove the "CC" prefix on some of the actions, as we're already within the scope of rules_cc.
* Remove the "all" prefix, since the plural "actions" should already imply this.
* Ensure all action types sets end with "_actions"
* Refactor some action type sets to be constructed from other (eg. link actions = link executables + link dynamic libraries).
* Remove the redundant "all_compile_actions", since it was equivalent to "all_cc_compile_actions"

BEGIN_PUBLIC
Implement cc_toolchain_config rule and cc_legacy_file_group rule.
Note that this rule is in the impl/ directory because we require users to use the cc_toolchain_config rule via the cc_toolchain macro that we will define later, to ensure that parameters such as `compile_files` are passed correctly.

Similar to the previous CL, this CL is to ensure that we agree on the relationship between each different type.
This will also allow for developing two things in parallel:
* The rules that generate these providers.
* Toolchain validation, and conversion to the cc_toolchain_config_lib providers.
