feat: support using go_install or go_build if the asset for the platform isn't released in GitHub Releases

[suzuki-shunsuke]

Close #2132

Features

This pull request adds a new field build to Registry settings.
This enables to install packages by go_install or go_build on platforms where prebuilt binaries aren't published.

Example

This is an example usage of the new field build.

packages:
  - type: github_release
    repo_owner: suzuki-shunsuke
    repo_name: tfcmt
    asset: tfcmt_{{.OS}}_{{.Arch}}.{{.Format}}
    format: tar.gz
    supported_envs:
      - linux
    build:
      type: go_build
      files:
        - name: tfcmt
          src: ./cmd/tfcmt
          dir: tfcmt-{{trimV .Version}}

supported_envs is linux because prebuilt binaries are published only for linux.
On platforms other than supported_envs, aqua installs tfcmt by go_build.

go_install is also available.

    build:
      type: go_install
      path: github.com/suzuki-shunsuke/tfcmt/v4/cmd/tfcmt

If go_build failed on windows/arm64 and we'd like to exclude windows/arm64, excluded_envs is available.

    build:
      type: go_build
      excluded_envs:
        - windows/arm64
      files:
        - name: tfcmt
          src: ./cmd/tfcmt
          dir: tfcmt-{{trimV .Version}}

If we'd like to disable build in version_overrides, enabled is available.

build:
  enabled: false

Why not overrides?

Of course, we can do the same thing with overrides.

packages:
  - type: go_build
    repo_owner: suzuki-shunsuke
    repo_name: tfcmt
    files:
      - name: tfcmt
        src: ./cmd/tfcmt
        dir: tfcmt-{{trimV .Version}}    
    overrides:
      - goos: linux
        type: github_release
        asset: tfcmt_{{.OS}}_{{.Arch}}.{{.Format}}
        format: tar.gz
        files:
          - name: tfcmt

This example has only one element in overrides, but if overrides has multiple elements, build makes the code simpler.
And build makes the intension clearer.
