Add missing identifiers for RSA and elliptic curves

[samitolvanen]

optee-utee is missing a few algorithm and attribute identifiers required for implementing AOSP KeyMint TA [1]. Add the missing RSA and ECC constants.

Merged, thanks!
BTW, If your TA doesn't require the std (means all third-party crates it has imported don't need std) it's recommended to use our no-std branch which is more up-to-date with OPTEE version and has better performance. If you're interested in it see here: https://github.com/apache/incubator-teaclave-trustzone-sdk/tree/no-std

Yes, we've been using the no-std branch. Do you cherry-pick changes from master to the no-std branch, or is there something I should do to get this merged there too?

I'll do that.
It's nice to open the PR on no-std branch the next time, thanks!
