rustc_target: Remove some redundant target properties

`is_like_emscripten` is equivalent to `os == "emscripten"`, so it's removed.
`is_like_fuchsia` is equivalent to `os == "fuchsia"`, so it's removed.
`is_like_osx` also falls into the same category and is equivalent to `vendor == "apple"`, but it's commonly used so I kept it as is for now.

`is_like_(solaris,windows,wasm)` are combinations of different operating systems or architectures (see compiler/rustc_target/src/spec/tests/tests_impl.rs) so they are also kept as is.

I think `is_like_wasm` (and maybe `is_like_osx`) are sufficiently closed sets, so we can remove these fields as well and replace them with methods like `fn is_like_wasm() { arch == "wasm32" || arch == "wasm64" }`.
On other hand, `is_like_solaris` and `is_like_windows` are sufficiently open and I can imagine custom targets introducing other values for `os`.
This is kind of a gray area.
