0eeb02c0 - [syntax-errors] Detect single starred expression assignment `x = *y` (#17624)

[syntax-errors] Detect single starred expression assignment `x = *y` (#17624) ## Summary Part of #17412 Starred expressions cannot be used as values in assignment expressions. Add a new semantic syntax error to catch such instances. Note that we already have `ParseErrorType::InvalidStarredExpressionUsage` to catch some starred expression errors during parsing, but that does not cover top level assignment expressions. ## Test Plan - Added new inline tests for the new rule - Found some examples marked as "valid" in existing tests (`_ = *data`), which are not really valid (per this new rule) and updated them - There was an existing inline test - `assign_stmt_invalid_value_expr` which had instances of `*` expression which would be deemed invalid by this new rule. Converted these to tuples, so that they do not trigger this new rule.
