Paul Berry 8aa48712be Patterns parsing: recover from patternVariableDeclaration non-statement.

Previously, if a pattern variable declaration appeared outside of a
function or method, the parser would get very confused.  Now it
recognizes the situation, issues a comprehensible error message, and
replaces the pattern with a synthetic identifier token so that the
analyzer AST is somewhat sensible.

Fixes #51322.
