Implements the approved API from dotnet#109019. ValueAsnReader is a ref struct counterpart to AsnReader that operates on ReadOnlySpan<byte> instead of ReadOnlyMemory<byte>. Also adds comprehensive dual-testing via AsnReaderWrapper so all reader tests exercise both AsnReader and ValueAsnReader. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Implements the new public ValueAsnReader in System.Formats.Asn1 (span-based, stateful ASN.1 reader) and updates several cryptography/X.509/PKCS components to use it in place of the internal AsnValueReader, with accompanying test refactoring to exercise both reader implementations.
Changes:
- Add
ValueAsnReaderAPIs (e.g.,ReadSequence,ReadSetOf,ReadUtcTime,ReadObjectIdentifier, etc.) in System.Formats.Asn1. - Refactor System.Formats.Asn1 reader tests to run against both
AsnReaderandValueAsnReadervia a wrapper. - Replace usages of internal
AsnValueReaderwithValueAsnReaderacross X509/PKCS/Common crypto codepaths and generated ASN.1 decoders.

This implements
ValueAsnReader, and replaces the old internalAsnValueReaderwith the new public one in some places.This is not meant to be a comprehensive replacement of
AsnValueReaderyet, as that makes this pull request even more significant.This pull request is broken up in to two commits: the new
ValueAsnReaderin theSystem.Formats.Asn1package along with the tests, and the second commit is using it inasn.xslt, and updating all files as required that use theAsn-suffixed types.We can split this pull request in to two separate PRs if preferred. However I wanted to see some real usage of the new APIs in functional unit tests of other areas to help validate the shape / implementation.
Fully removing the internal
AsnValueReaderwill be a follow up pull request.Closes #109019.
