fix(eslint-plugin): [no-unnecessary-parameter-property-assignment] account for parameter reassignment - #12880

…account for parameter property reassignment (#26955)

Ports typescript-eslint/typescript-eslint#12880. After `name = name.trim()`, copying the reassigned parameter with `this.name = name` is necessary; Oxlint previously reported it and suggested removing it.

Track writes to the constructor parameter binding in source order, including nested assignments and arrow IIFEs. Later writes and writes to unrelated or shadowed bindings do not suppress reports. Includes all upstream regression cases and checks Oxc's removal suggestions.
