The hypervisor::haxm module is only available for cfg(windows), so make
the cfg wrapping the tests use the same condition as the haxm module.
In theory, HAXM is available on Linux, but we don't support that; this
change makes the cfg checks consistent so that building and testing with
--features=haxm on Linux can succeed (without actually enabling HAXM).

On Intel, new noncoherent DMA mem flag can be set to allow KVM to
recognize guest cache setting for EPT, which allows WC attribute to be
applied to ensure guest memory access is synchronized in noncoherent DMA.
Unlike previous POC for new device attribute, this uses new added flag
for mem slot.

Updates are made to source and documentation.
This more accurately represents the currently supported platforms of
Android/Linux and Windows, without unexpectedly including other
unix-like operating systems.
Command to reproduce:
$ find . -type f -not -path '*/\.git/*' | xargs -I {} sed -i 's/cfg(unix)/cfg(any(target_os = "android", target_os = "linux"))/g' {}
$ cargo fmt
md files manually updated to fix line lengths.
Renaming `unix` modules to `linux` will be done in a later CL.

crosvm has never actually supported running on a 32-bit x86 host, only
x86-64. Remove the cfg(target_arch = "x86") checks throughout the tree
to make this clear (and to simplify the code).
This doesn't affect the code running inside the guest, which can still
be a 32-bit x86 operating system if launched via --bios, for example.

VcpuRunHandle was only used to signal immediate_exit on unix platforms;
it was unnecessary on Windows. It is replaced with a new
VcpuSignalHandle abstraction that is only implemented for cfg(unix).
This commit moves the thread local storage out of hypervisor and into
the unix/vcpu.rs code; it does not need to be duplicated in each
hypervisor backend.

We are going to need to start passing a new arch-dependent configuration
parameter to KvmVm::new in addition to protection_type. Since we can't
[cfg] a function argument, and to avoid churning the tests the next time
we need another argument, let's create a hypervisor::Config struct and
start passing protection_type that way.

crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.
