Subject: [PATCH] fix: support `devServer.server` option, avoid deprecation
 warning

Closes #7024
Fixes #7118

I choose to not merge the PR because I don't want add additional ways
to configure https for dev server (`--http2` command line argument,
`process.env.HTTPS`, etc.)

In the current implementation, `spdy` can only be configured by setting
`{ devServer: server: { type: 'spdy' } }`.
This is a deliberate choice, because SPDY support in Node.js 15+ is
broken anyway. I don't want bother refactoring the old code to
accommodate this broken feature.
