Expose not normalized yParity as _yParity in authorization list #5091
Description
Describe the Feature
Hi,
It would be nice if we could have access to the not normalized yParity using _yParity similar to _s value.
that's because ethers normalizes 0x1b to 1 etc.. due to the issue reported for L2 nodes here: #4985
there is this other issue that says just use an old version that is not a good strategy long term:
#5084 (comment)
But in reality other issues show that those values are not necessarily meant to be normalized according to ethereum spec only value 0 or 1 should be okay 2 << 8
see:

Ideally it would be nice to be able to get the unnormalized/untouched yParity, if the yParity needs to be normalized for reasons i don't really understand could we have it as _yParity similar to _s for s value in other places.
