Merge #19508: Work around memory-aliasing in descriptor ParsePubkey

fa8a99258947a9ee3749fa472180542920cd471c Work around memory-aliasing in descriptor ParsePubkey (MarcoFalke)
Pull request description:
While this is not undefined behaviour, the memory aliasing trick is confusing when reading the code. Having `a.size()==0` and then access `a[0]` works in this particular case, but should probably be avoided to harden the code for the future.
