[TS] Support `push` invocation in `InstanceCallExpr` resolution

[CaelmBleidd]

Current implementation is

        // TODO write tests
        if (expr.callee.name == "push" && expr.instance.type is EtsArrayType) {
            return scope.calcOnState {
                val resolvedInstance = resolve(expr.instance)?.asExpr(ctx.addressSort) ?: return@calcOnState null
                val lengthLValue = mkArrayLengthLValue(
                    resolvedInstance,
                    EtsArrayType(EtsUnknownType, dimensions = 1)
                )
                val length = memory.read(lengthLValue)
                val newLength = mkBvAddExpr(length, 1.toBv())
                memory.write(lengthLValue, newLength, guard = ctx.trueExpr)
                val resolvedArg = resolve(expr.args.single()) ?: return@calcOnState null

                // TODO check sorts compatibility
                val newIndexLValue = mkArrayIndexLValue(
                    resolvedArg.sort,
                    resolvedInstance,
                    length,
                    EtsArrayType(EtsUnknownType, dimensions = 1)
                )
                memory.write(newIndexLValue, resolvedArg.asExpr(newIndexLValue.sort), guard = ctx.trueExpr)

                newLength
            }
        }

We need to check it and fix if required
