[ruby/prism] Fix crash when using arithmetic expressions in pattern matching
When arithmetic expressions like -1**2 are used in pattern matching contexts,
Ruby crashes with "Unexpected node type in pattern matching expression: PM_CALL_NODE".
This happens because the Prism parser creates PM_CALL_NODE for arithmetic operations,
but Ruby's pattern matching compiler doesn't handle call nodes.
This fix adds validation to reject PM_CALL_NODE in pattern contexts with a proper
syntax error.
