Cleanup extra check configs in bootstrap

Browse Source 
- `target_os=watchos`: no longer relevant because there are now proper
   targets `*-apple-watchos`
 - `target_arch=nvptx64`: `nvptx64-nvidia-cuda`
 - `target_arch=le32`: target was removed
   (https://github.com/rust-lang/rust/pull/45041)
 - `release`: was removed from rustfmt
   (https://github.com/rust-lang/rustfmt/pull/5375 and
   https://github.com/rust-lang/rustfmt/pull/5449)
 - `dont_compile_me`: was removed from stdarch
   (https://github.com/rust-lang/stdarch/pull/1308)

Also made some external cfg exception mode clear and only activated for
rustc and rustc tools (as to not have the Standard Library
unintentionally depend on them).
