This change pushes down the memoization of RawData from X509Certificate2 to X509Certificate (so we don't have it memoized twice). This is because the RawData property on the ICertificatePal may allocate, such as the case of the OpenSSL PAL.

Since the memoized value is available in the base X509Certificate, use it where appropriate such as creating the hash of a certificate. This also makes a small optimization of using the stack for the intermediate bytes between the hash and the hex value.

See #103814 for some background.
