Resource API deprecation, and preparation for 2.x.x. & back port improvements

[nomisRev]

Propose the deprecate almost the entirety of the Resource API, as discussed in the 2.x.x PR.

Deprecated APIs

• zip: composing resource using resource { f(bind(), bind()) } supports arity-n
• parZip: can be inherited from Arrow Fx Coroutines methods, and naturally compose inside the DSL.

flatMap & co

For Either we've decided to keep these methods, should we keep them for Resource as well?

• map/tap/flatMap: this methods can be replaced entirely by the DSL, should we keep

resA.flatMap {
  resB
}

resource {
  resA.bind()
  resB.bind()
}

resA.map(f)
resource { f(resA.bind()) }

resA.tap(f)
resource { resA.bind().also(f) }
