Add attachment driven entity luminance providers & data component driven item luminance providers

[no-name-provided]

Is your feature request related to a problem? Please describe.
No, not really. They are motivated, though:

Your documentation implies that you want to encourage data-driven integration where possible. Attachments are a (or perhaps the) way for NeoForge devs to save synchronized data to arbitrary entities. Data components are their rough equivalents for item stacks.

If these providers were available by default, I wouldn't have needed to write my plugin.

Describe the solution you'd like
Create 4 new default providers:

1. An entity provider that accepts a Boolean attachment and a light level and returns the light level when the attached value is true
2. An item provider that accepts a Boolean data component and a light level and returns the light level when the component's value is true
3. An entity provider that accepts a Byte attachment and returns the attached value
4. An item provider that accepts a Byte attachment and returns its value

Describe alternatives you've considered
These are trivial to implement, so I went ahead and did so (the one I needed, anyway).
