[rpcexplorer] Simplify local development of the RPC Explorer.

This adds LUCI_RPCEXPLORER_LOCAL_BUILD_DIST env var that points
to a `dist` folder with local RPC Explorer build to use instead
of the build embedded into the Go code.

To work on RPC Explorer:

```
# Point to the dist directory.
export LUCI_RPCEXPLORER_LOCAL_BUILD_DIST=.../web/rpcexplorer/dist

# Run some LUCI server.
cd examples/appengine/helloworld_v2
go run main.go

# Start to continuously rebuild RPC Explorer on changes.
cd web/rpcexplorer
npm run watch

# Hack on RPC Explorer code. Observe the effect by visiting
# http://127.0.0.1:8800/rpcexplorer/
```

luci-go: LUCI services and tools in Go

GoReference

Installing

LUCI Go code is meant to be worked on from an Chromium infra.git checkout, which enforces packages versions and Go toolchain version. First get fetch via depot_tools.git then run:

fetch infra
cd infra/go
eval `./env.py`
cd src/go.chromium.org/luci

It is now possible to directly install tools with go install:

go install go.chromium.org/luci/auth/client/cmd/...@latest
