Roland Shoemaker 1cd71689f2 crypto/x509: rework fix for CVE-2025-58187
In CL 709854 we enabled strict validation for a number of properties of
domain names (and their constraints). This caused significant breakage,
since we didn't previously disallow the creation of certificates which
contained these malformed domains.

Rollback a number of the properties we enforced, making domainNameValid
only enforce the same properties that domainToReverseLabels does. Since
this also undoes some of the DoS protections our initial fix enabled,
this change also adds caching of constraints in isValid (which perhaps
is the fix we should've initially chosen).

Updates #75835
Fixes #75828
