Paul Gschwendtner f8c02b69b9 refactor(compiler-cli): restrict read option values for signal-based queries (#54257)
The `read` option for queries can rely on lexical variables inside the
class. These constructs are fine from a technical perspective in
TypeScript, but in practice, when the component/directive definition is
being created, the read value is extracted into the definition,
**outside** of the class. This breaks `this` references.

To fix this, we are restricting the `read` option to literal values.
Similar to `descendants`. Literal references are in practice constructs
like:

 - `read: bla.X`
 - `read: X`

 where `bla` or `X` is never a `ThisKeywoord`- hence fixing the issue
 and also simplifying the patterns for easier single file compilation.
