Refactor how TLS versions get enabled

This brings it closer in line to how QUIC_VERSION_99 is handled and sets up the
flag to be switched to a reloadable flag (blocked on being enabled). In particular,
AllSupportedVersions() now returns versions that include PROTOCOL_TLS1_3 for the
handshake_protocol.

When a TLS version is in use, it is safe to assume that
ParsedQuicVersion::KnowsWhichDecrypterToUse always returns true. This is because
KnowsWhichDecrypterToUse is enabled for QUIC_VERSION_47 and above, while TLS versions
only exist when CRYPTO frames are in use, which is currently only transport version 99.
