CryptoPkg/TlsLib: pre-compute OpensslCipherLength in TlsCipherMappingTable

CryptoPkg/TlsLib: pre-compute OpensslCipherLength in TlsCipherMappingTable

In the next patches, we'll need the lengths of the
TLS_CIPHER_MAPPING.OpensslCipher string fields. These lengths can be
computed at build time; add the new field "OpensslCipherLength", and
introduce the MAP() macro for populating it.

While at it, add some horizontal whitespace to "TlsCipherMappingTable",
and add a comma after the last element. This will come handy in a later
patch.

(The patch does not change the first two columns of
"TlsCipherMappingTable", which can be easily verified with "git show
--word-diff".)
