schannel: when importing PFX, disable key persistence

By default, the PFXImportCertStore API persists the key in the user's
key store (as though the certificate was being imported for permanent,
ongoing use.)

The documentation specifies that keys that are not to be persisted
should be imported with the flag PKCS12_NO_PERSIST_KEY.
NOTE: this flag is only supported on versions of Windows newer than XP
and Server 2003.

This is take 2 of the original fix. It extends the lifetime of the
client certificate store to that of the credential handle. The original
fix which landed in 70d010d and was later reverted in aec8d30 failed to
work properly because it did not do that.

Minor changes were made to the schannel credential context to support
closing the client certificate store handle at the end of an SSL session.
