feat(es/plugin): Add AST query API

[kdy1]

Description:

Typically, finding an ast node involves 3 ~ 8 levels of nested pattern matching, but I think it can be reduced with this.

• Basically, it consists of a pattern matcher and an operator
• Pattern matcher can be written using query! macro
• $n is one capture group.
• $n can capture an expression, pattern, or a statement
• The operator is a closure (need more thinking)
• Operators are called once for each target node
• Operators are called with the target AST node of the query by default and called with captured node if there are one or more capturing ($n).
