rustc_target: Further cleanup use of target options

Follow up to https://github.com/rust-lang/rust/pull/77729.

Implements items 2 and 4 from the list in https://github.com/rust-lang/rust/pull/77729#issue-500228243.

The first commit collapses uses of `target.options.foo` into `target.foo`.

The second commit renames some target options to avoid tautology:
`target.target_endian` -> `target.endian`
`target.target_c_int_width` -> `target.c_int_width`
`target.target_os` -> `target.os`
`target.target_env` -> `target.env`
`target.target_vendor` -> `target.vendor`
`target.target_family` -> `target.os_family`
`target.target_mcount` -> `target.mcount`
