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.

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
* update two explicit references to jdk14 to just jdk, which no longer
points at jdk8 after #89731.
* patch an explicit -XX:+UseConcMarkSweepGC to -XX:UseG1GC, as the
former now throws an error (after having been deprecated since jdk 9)
