Description

Source literals should not have a dedicated expression type of SourceLiteralExpression. These work exactly the same as VariableExpression, so we should just use that. And then the list of known source literals can be handled in the validation and transpilation layers.

This is a breaking change, so we should do this before v1.0.0 lands.

Research direction

Start by tracing SourceLiteralExpression through the AST, validation, and transpilation layers, then compare it with VariableExpression. Done means source literals use VariableExpression and their known-literal handling resides in validation and transpilation, with the relevant existing tests passing.
