Add *-espidf target triple mappings
Fixes
This makes it possible to workaround cc/bindgen issues with esp-rs
projects by using only environment varaibles (TARGET_CC, CLANG_PATH,
etc).  Without this, it requires modifying each crate's build.rs that
you try to depend on to add a target option passed along to clang.
