[Feat]: Add the all build tag to extensions

[AndersBennedsgaard]

Is your feature request related to a problem? Please describe.

Since we have a lot of different build tags for different components, and not all tools (like gopls and golangci-lint) supports ignoring build tags, it means that you have to manually add all these build tags when you use these tools. This can for example be seen here:

zot/.github/workflows/golangci-lint.yaml

Line 34 in e5eacaa

args: --config ./golangcilint.yaml --enable-all --build-tags debug,needprivileges,sync,scrub,search,userprefs,metrics,containers_image_openpgp,lint,mgmt,imagetrust ./cmd/... ./pkg/...

Whenever a new build tag is introduced (such as coming from a new extension), we have to add there here

Describe the solution you'd like

I propose that we add an additional tag called all wherever we use build tags, such that we only have to use that tag when building the full Zot binary with all extensions, and gopls is easier to configure:

// +build sync all
