Fixes up the usage of patches/postInstall. Also removes `stdenv.lib` and
other minor tweaks.

d81e4d9f66 contained some minor fixes to the yosys derivation
that make it a little easier to read and maintain. Incorporate those.

These plugins can be included in a closure, along with the `yosys`
derivation, and they will be automatically picked up for use. For
example, this allows you to include 'yosys-bluespec' in your
`buildInputs`, and then immediately run:
$ nix-shell -p yosys yosys-bluespec yosys-ghdl
$ yosys -m bluespec -p 'help read_bluespec'
$ yosys -m ghdl -p 'help ghdl'
These two plugins are a bit experimental, admittedly, but they are good,
clean examples of how to write and use the yosys plugin infrastructure,
and make it easy to test updates, etc.

By default, when yosys looks for plugins with the `-m` flag or `plugin`
command, it always looks in `YOSYS_PREFIX/share/yosys/plugins` for a
`.so` file, and loads that.
By design, this is intended to be a single, global, mutable location
such as `/usr/share/yosys/...` on disk, and plugins are supposed to
install their `.so` files here after yosys is installed, and they all
coexist together. Obviously, this won't work for us, but users might
expect these plugins to still work. More importantly, they won't want to
add special cases to their build systems.
Instead, to allow Nix users to use yosys plugins with the same UX (e.g.
natively call `plugin bluespec` or `-m ghdl`), we add a patch to yosys
that allows it to search a new `NIX_YOSYS_PLUGIN_DIRS` search path
environment variable. In tandem, we add a setup hook that adds to this
search path if a package has a `$out/share/yosys/plugins` directory.
Thus, it's enough to just include `yosys`, and any package that has a
yosys plugin in `$out/share/yosys/plugins`, and you can load it with
`-m` or the `plugin` command.
We could use a style like the haskellPackages set, where the set of
packages are "encased" in a lambda, and we pass packages that are
compatible with that version of the compiler:
haskell.packages.ghc8102.ghcWithPackages (p: with p; [ ... ])
but, realistically, there will probably only ever be one version of
yosys and one set of compatible plugins, so this seems overdone.

This unreleased version of GHDL fixes a bunch of bugs. It also contains
a few internal API changes for synthesis support -- required by the GHDL
yosys plugin.
Ideally, we can just remove this when 0.38 comes out.

Some applications, like the Jetbrains IDEs, check for a suffix to
determine if a stable JDK is used.
This flag was already passed for older versions, but it got lost for
OpenJDK 14+.
* fixed buildInputs and nativeBuildInputs for cross compilation
* don't use pkgconfig alias
* simplified patchPhase
* made the version variable overridable in preBuild
Instead of copying the whole dart derivation to bin/cache/dart-sdk
directory, just symlink it.
Also, make sure that the flutter is build from dart passed as a
parameter.
Before:
/nix/store/p3avfmvd0yrjpwwml7vvqbjin5vacx2k-flutter-stable-1.22.0 2084894968
After:
/nix/store/750k4z1yj5xsw7ymmwvn7cfjjzkaygzg-flutter-stable-1.22.0 1647047080
We can use use `stdenv.hostPlatform.isStatic` instead, and move the
logic per package. The least opionated benefit of this is that it makes
it much easier to replace packages with modified ones, as there is no
longer any issue of overlay order.

Upstream NextPNR has moved to disable the GUI by default; it tends to
cause the most complications/bug reports and has various complexities
and failure modes (e.g. I've still had problems getting it working
efficiently on my Ice Lake laptop.)
Instead, disable GUI support by default, and add a new `nextpnrWithGui`
derivation that enables it. This cuts the closure size down by 40ish
percent (~800MB -> ~500MB) and makes it a neglibile amount faster.
It also fixes two bugs:
1) We were using the old `ICEBOX_ROOT` parameter for ice40 support,
now known as `ICESTORM_ICE40_PREFIX`, and
2) the CMake option `SERIALIZE_CHIPDB` was renamed to `..._CHIPDBS`
(with an 'S' suffix) which should speed up the build at the cost
of RAM usage

NixOS 20.0.9's default NVIDIA video driver version is 455.38, which supports CUDA 11.1.1.
**Things to note:**
- [ ] Users with nvtop installed may need to upgrade their nvtop installation due to caching behavior
