`prefix` or `public` keys break `meta`

Describe the bug This data model file compiles successfully:

cubes:
  - name: meta_prefix
    sql: SELECT 123

    measures:
      - name: count
        type: count
        meta: 
          my_prefix: qwerty

However, the following data model file would not compile (take a close look at meta):

cubes:
  - name: meta_prefix
    sql: SELECT 123

    measures:
      - name: count
        type: count
        meta: 
          prefix: qwerty

It emits the following error:

cubes/meta_prefix.yml:8
        "prefix": qwerty
                  ^

ReferenceError: qwerty is not defined

Apparently, there's an issue with data model validation: prefix is not accepted inside meta if it has a value of the string type. Passing a boolean or a numeric value works.

Might be related to how Cube validates prefix inside views (docs).

Expected behavior It should be allowed to use prefix inside meta on cube/view members.

Apparently, public also breaks meta in the same way.
