Hi
This is follow up for the "Openssl1.1 replacement proposal" https://edk2.groups.io/g/devel/topic/96741156.
openssl 3.0 POC result is shown at https://github.com/tianocore/edk2-staging/blob/OpenSSL11_EOL/CryptoPkg/Readme-OpenSSL3.0.md
The size increase is reduced to ~10%.

In order to achieve maximum size optimization for openssl 3.0, we updated openssl 3.0 branch and recorded to https://github.com/liyi77/openssl/tree/openssl-3.0-POC.
To help the community review and feedback the openssl 3.0 change and plan to openssl upstream in the future, we should avoid personal branch usage.

The proposal is to:

  1.  Create *an edk2 fork of openssl* under https://github.com/tianocore
  2.  Create *an edk2 branch* to hold all update for support https://github.com/tianocore/edk2-staging/tree/OpenSSL11_EOL
  3.  Add git submodule of the edk2 fork of openssl to the OpenSSL11_EOL.

Thank you
Yao, Jiewen
