When cpu value is not enough to distinguish between two toolchains, we use the compiler value. In that case, the user needs to specify the compiler value for all cc_toolchain_config rules, even for the ones with unique cpu. This cl fixes the allowed values in the compiler attribute to account for the values from unique toolchains.

This will make sure the copybara export is reversible, which is needed for setting up copybara workflow for importing github PRs.

And fix an error where we added previously unseen action_names to the dictionary of familiar ACTION_NAMES, so later when we would encounter them, we would treat them as variables, not as string literals
eg
env_set {
action = "a"
}
would translate to
env_set(
actions = [a],
)
which is, obviously wrong.

If toolchain A and B need feature f, but toolchain C doesn't, the generated declaration statement for feature f would be:
if ctx.attr.cpu == 'A.cpu':
f = feature(...)
elif ctx.attr.cpu == "B.cpu" and ctx.attr.compiler == "B.compiler":
f = feature(...)
else:
fail("Unreachable")
This will break the rule implementation in the case of toolchain C because it will reach the fail("Unreachable") although it doesn't need to declare feature f
This cl fixes that

If an action_config's name doesn't appear in the action_names.bzl, eg action-a.b+c, in it's assignments statement we would declare it as:
action_a.b+c_action = action_config( ...
This cl fixes it to create the action_config variable with the +, - and .
It also adds tests for action_config
