rescan in formatter if followed unary literal

[Kingwl]

Fixes #29330

after track，I found the reason of the assert failed caused the -1 has been scanned as prefixUnaryExpression -> Numeric Literal, i have rescan the literal and merge the prefix expression and number literal to a signal literal

@sandersn is this the right approach?

I think in general, instead of rescanning numeric literal, we usually handle prefixUnaryExpression for the negative numbers. eg. check serializeTypeNode
