The majority of the time objc_compile is identical to C/C++ compiles.
Because of this I think by default all of those flags should apply here.
This is a bit funny since the current builtin toolchain doesn't support
Objective-C at all and that's only in the apple_support toolchain, but
new toolchains using these rules may want to support this.
Without this things like `--objccopt` just don't work out of the box.
BEGIN_PUBLIC
Add `@rules_cc` to generated docs
Ensures when docs are generated that the `@rules_cc` prefix is used for anything that appears to come from the repo.

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.
BEGIN_PUBLIC
Remove experimental_enable_rule_based_toolchains flag
Rule-based toolchains will not be gated by a flag when released with rules_cc v0.0.10. Also, this flag is unfortunately inherently incompatible with --experimental_exclude_starlark_flags_from_exec_config.

Fix rule-based implementation of runtime_library_search_directories

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.

BEGIN_PUBLIC
Add support for implicit include directories to rule-based toolchains
Reorients the `cc_toolchain.cxx_builtin_include_directories` attribute so it is expressed as an attribute on `cc_args` and `cc_tool` to signify that the tools or arguments imply include directories that Bazel's include path checker should allowlist. This moves the allowlist to the source of truth that implies these directories.

BEGIN_PUBLIC
Remove feature requirements from tools.
It's such a niche use case, adds a fair amount of complexity, and there are multiple alternatives available:
* Now that we're using rule based things, you should just be able to add a bazel flag and select on it in your tool definition.
* If you really want precisely that behaviour, you can make your feature add "--use-foo-tool" to the args, and make your tool a wrapper tool that reads the command-line argument, and if provided, invokes a different tool.

This CL is an alternative to unknown commit. I left the other CL seperately, because I wasn't 100% sure that we'd agree to this, since this is an API change.
I did it this way because I believe it's much less hacky, and it also allows us to format things that aren't variables.
BEGIN_PUBLIC
Add support for select'ing on cc_args(args=...).
This is quite tricky because the one parameter was being split into two in a macro, one of type label and the other of type string.
For example, `args = ["--foo", format_arg("--bar=%s", "//path/to:bar")]` was rewritten by the macro to `args = [json.encode(struct(format_type="raw", format="foo")), json.encode(struct(format_type="format_arg", format="--bar=%s", value=0))], variables = ["//path/to:bar"]`.
To allow it to work with selects, we need to ensure that we don't perform post-processing on the inside of the select. To solve this, we:
* Ensure that args only take strings
* Provide a seperate parameter for substitutions.
This new mechanism also has the useful property that we can now format things that are not variables. For example, I can do the following:
```
directory(name = "sysroot", ...)
cc_args(
name = "sysroot_arg",
args = ["--sysroot={sysroot}"],
format = {
":sysroot": "sysroot"
}
)
```
