feat(mason): allow packages that use MasonGenerator to acess BrickVariableProperties.

[renancaraujo]

Description

There is a way of generating files from bundled bricks. That evolves mostly by calling MasonGenerator's hooks.preGen, hooks.postGen and generate methods.

Example (extracted from here)

final vars = <String, dynamic>{};

// Run pre gen
await generator.hooks.preGen(vars: vars, onVarsChanged: (v) => vars = v);

// create the files
await generator.generate(target, vars: vars, logger: logger);

// Run post gen
await generator.hooks.postGen(vars: vars, onVarsChanged: (v) => vars = v);

The problem with that approach is that it disregards the prompts, default values, value types, and allowed values specified in the vars property in the brick.yaml file.

This issue requests an API that allows access to that property directly from a MasonGeenrator or subclass.

One suggestion is to save a BrickYaml instance as property of MasonGenerator

Requirements

• An API that allows access to that property directly from a MasonGeenrator or subclass.

Additional Context

This is a request that would make life at very_good_cli easier.

Opened a POC for this on #1076
