Subject: [PATCH] crypto: fix performance regression

https://github.com/nodejs/node/commit/e559842188f541b884abff2ffad4d2d3e1b841a6
made writable/readable computed with a legacy mode if the properties
are written to.

LazyTransform still unecessarily wrote to these properties causing a
performance regression.

Fixes: https://github.com/nodejs/node/issues/31739
