What this PR does / why we need it:

The recent developments on the plugin framework and API introduced many changes and features, alongside a new major version of the plugin API. This PR syncs the SDK Go to make it comply to the new plugin API major.

Besides tons of new features have been added, they are not addressed by this PR. End users of the SDK Go should not expect any breaking changes nor novelties, besides:

• Having new types available for sdk.ExtractRequest.SetValue, reflecting the new ones introduced recently (e.g. booleans)
• Plugins build on top of the new SDK will require a plugin API 3.0.0, which will be rolled out in Falco 0.35 (end of May 2023). This means that plugins built with a Go SDK version >= 0.7.0 (still to be released) will not work with Falco version <= 0.34.1.
