parser: Add support for variables and identifiers in function body

This commit adds support for variables and identifiers in the function
body of the parser, stored as a vector.

However, at this point, identifier resolution is not fully implemented,
and we currently accept identifiers without checking if they can be
resolved. This is a known limitation that will be addressed in a future
commit once hash-tables are added to the parser.
