misc: add klayout

[proppy]

Based on @klayoutmatthias's fork of https://github.com/conda-forge/staged-recipes/pull/20396.

Wanted to just build the CLI to aligned with #250 and #193 but couldn't find a build option to disable QT while still keeping klayout_main.

Fixes #175

[proppy]

LGTM.

Let's not merge before we get the CI passing.

@mithro yay it's green! https://github.com/hdl/conda-eda/actions/runs/3751563916/jobs/6372696825 \o/

[mithro]

Looks like the CI is still generally broken however?

[proppy]

@mithro in my experience the CI is generally flaky for some of the f4pga packages (vtr, yosys-osx) to but I don't see any issues in that runs for the silicon toolchain packages.

[mithro]

Merge away then?

[proppy]

I suspect @ajelinski will want us to audit the warnings and squash commits first!

Identified 4 cluster of warnings:

• WARNING rpath /home/runner/work/conda-eda/conda-eda/workdir/conda-env/conda-bld/klayout_1671649256384/_build_env/lib is outside prefix which I believe are due to cdt.

• WARNING Failed to get_static_lib_exports which according to can safely be ignored https://github.com/hdl/conda-eda/pull/165#issuecomment-1059282395

• WARNING (klayout,bin/strmclip): Needed DSO lib/libQt5Core.so.5 found in ['qt'] but ['qt'] not in reqs/run, (i.e. it is overlinking) (likely) or a missing dependency (less likely) which need fixing.

• WARNING (klayout): run-exports library package pkgs/main::icu-58.2-he6710b0_3 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it tobuild/ignore_run_exports) which need fixing.

A few remaining warnings from https://github.com/hdl/conda-eda/actions/runs/3758645638/jobs/6387239942

those are cdt so I don't think they are required.

assuming those are unused?

Done.

and rebased.

Merging since the build is green and remaining warnings were addressed per https://github.com/hdl/conda-eda/pull/268#issuecomment-1363176244
