Split runtime/interpreter/value.go into multiple files

[darkdrag00nv2]

Issue to be solved

The runtime/interpreter/value.go file is huge. Even the GitHub syntax highlighting gets disabled on PR reviews because of the huge size.

Suggested Solution

We should consider splitting the file into different files. A decent split can be:

1. value_collections.go
2. value_numbers.go
3. value_options.go
   .. More if needed ..

value_test.go would have to be split accordingly.

Agreed, it's grown significantly and new value types have already been added in new files.

Logistically, the plan is to merge feature/stable-cadence into master soon, when all maybe features have been merged (e.g. Entitlements). Once that is done, and before other major PRs are started which might touch value.go, we should split it up 👍
