Expose -debug and -ldflags build options

[razor-x]

@dexter93 I tired to get your PR working, but I kept getting errors due to the string passing / quoting issues.

I made a few changes and tested this version which is working. Feel free to incorporate these changes into you PR, or we can just try to get this one merged. Either is ok by me.

I am able to pass ldflags now like this which is a bit nicer UX for multiple flags.

      with:
        build: true
        build-ldflags: >-
          -X=main.AppVersion=${{ steps.meta.outputs.version }}
          -X=main.Foo=${{ inputs.foo }}

This looks like a better version indeed. Let's do this

@Snider any ETA on getting this merged? 😄 i'd love to use ldflags to set the binary version dynamically
