ci : add release job and include xcframework

[danbev]

This commit adds a release job that uploads the xcframework as an artifact and creates a release with the xcframework as an asset.

This job can be triggered manually and enables a pre-release tag name to be specified to that these releases can be distinguished from the regular releases more easily.

Resolves: #2886

@ggerganov Is it alright if I trigger this workflow manually and create a few pre-releases. I'll delete them when things are working as expected.

[ggerganov]

Yes, that's OK.

I'm not sure how I can test the manual workflow on this repository before it is actually commited. So I used my fork to run the manual workflow which created this pre-release. I've was able to test the xcframework using the following Package.swift file:

// swift-tools-version: 5.10
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "Whisper",
    targets: [
        .executableTarget(
            name: "Whisper",
            dependencies: [
                "WhisperFramework"
            ]),
        .binaryTarget(
            name: "WhisperFramework",
            url: "https://github.com/danbev/whisper.cpp/releases/download/danbev-testing-pre-release2/whisper-danbev-testing-pre-release2-xcframework.zip",
            checksum: "e3f34fb305d0b20b2d6203e79997719625e52f7e5eb1d20156adce6e8741ccd1"
        )
    ]
)

If the CI run succeeds then perhaps we can merge this and then I can run the workflow on this repo and verify that is works here as well 🤞

I ran the manual workflow which created a pre-release:

And I was able to run this using:

// swift-tools-version: 5.10
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "Whisper",
    targets: [
        .executableTarget(
            name: "Whisper",
            dependencies: [
                "WhisperFramework"
            ]),
        .binaryTarget(
            name: "WhisperFramework",
            url: "https://github.com/ggerganov/whisper.cpp/releases/download/danbev-testing-pre-release/whisper-danbev-testing-pre-release-xcframework.zip",
            checksum: "4e2379614a20c1a0694b7519d80cb41563120cce3af4fd1edf4b6c87af268d2e"
        )
    ]
)

I'm documenting this here as I'm going to delete this pre-release now.

Currently only the ios-xcode-build jobs artifact are included but this could be extended by adding more needed jobs.
