This is a followup to a conversation from #733
rustc sources used in rust analyzer can now be conditionally included in toolchains using the
RULES_RUST_TOOLCHAIN_INCLUDE_RUSTC_SRCSenviornment variable. Setting it totrueor1will enable it and any other value will disable it. I feel this gives users the most flexibility in how the decide to enable/disable it locally or in CI.
