Stabilize the `-Csplit-debuginfo` flag...
- ...on Linux for all values of the flag. Split DWARF has been
implemented for a few months, hasn't had any bug reports and has had
some promising benchmarking for incremental debug build performance.
- ..on other platforms for the default value. It doesn't make any sense
that `-Csplit-debuginfo=packed` is unstable on Windows MSVC when
that's the default behaviour, but keep the other values unstable.

Also change `executables` to true for linux-kernel and windows-uwp-gnu targets

This enables us to set more generic labels shared between targets. For
example `target_family="wasm"` across all targets that are conceptually
"wasm".

`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`

With this change, it's possible to build on a linux-gnu target and pass
RUSTFLAGS='-C target-feature=+crt-static' or the equivalent via a
`.cargo/config.toml` file, and get a statically linked executable.
This requires libc 0.2.79, which adds support for static linking with
glibc.
Add `crt_static_respected` to the `linux_base` target spec.
Update `android_base` and `linux_musl_base` accordingly. Avoid enabling
crt_static_respected on Android platforms, since that hasn't been
tested.
