Set up CI with Azure Pipelines (#72)

* Set up CI with Azure Pipelines

[skip ci]

* Fix %PLATFORM%

* Add Azure badge

* Try to make nimble happy with windows PATH

* rename steps [skip ci]

* Mixed up posix/windows in pipeline

* add missing ARCH: x86 to Linux32

* Linux "32bit" CI was actually 64-bit, remove it from now

* Try to workaround path issues in windows

* More crazy path workarounds + display gcc version (debug win 32-bit)

* keep the bash workaround in

* mingw path as separate task

* Let's start a fresh day bout against Azure

* fix powershell variable interpolation

* make all scripts verbose to debug MacOS Go libp2p daemon script

* Don't test on Azure macOS, xerrors issue due to Go version:
- https://github.com/libp2p/go-libp2p-daemon/issues/139
- https://github.com/status-im/nim-beacon-chain/pull/397
- https://github.com/golang/go/issues/32246

* polish + reduce verbosity [skip ci]
