gnu: nextpnr-ice40: Update to 0.8.

* gnu/packages/fpga.scm (nextpnr-ice40): Update to 0.8.
[snippet]: Use 'delete-all-but' defensive idiom and update comment.
[patches]: Apply unbundling patches.
[arguments] <:cmake>: New argument.
<#:configure-flags>: Add -DUSE_OPENMP=ON flag.  Adjust version string used with
-DCURRENT_GIT_VERSION.
<#:phases> {patch-source}: Streamline phase.
[inputs]: Remove imgui-1.86, which is now propagated by qtimgui.
[home-page]: Add trailing '/'.
[description]: Streamline description.  'FOSS' is implied by being part of the
Guix packages collection.
[license]: Correct to ISC license.
* gnu/packages/patches/nextpnr-gtest.patch: New file.
* gnu/packages/patches/nextpnr-imgui.patch: Likewise.
* gnu/local.mk (dist_patch_DATA): Register them.
