MdePkg: Split RNG protocol definitions
Move the structure definition to a common location that can be shared
with the RNG PPI. Move the algorithms to a common header that can be
referenced independent of the protocol.
Include the algorithm header in the interface header since the
algorithms are directly used in the interface and for compatibility
with existing code.

MdePkg: Add Random Number Generator (RNG) PPI
REF:https://github.com/tianocore/edk2/issues/10529
Adds a new PPI that serves the same purpose as EFI_RNG_PROTOCOL in
DXE. This PPI can be produced by a PEIM to provide a dynamic interface
to RNG services in PEI.

MdePkg: Add PeiRngLib
REF:https://github.com/tianocore/edk2/issues/10529
Adds a new PEI library instance for RngLib that uses the RNG services
provided by the RNG PPI.
This library instance will add a DEPEX on gEfiRngPpiGuid on modules
it links against. It can be used to allow PEIMs to get RNG support
over a dynamic interface.

SecurityPkg: Add RngPei
REF:https://github.com/tianocore/edk2/issues/10529
The `RngPei` PEIM can be used if RNG should be provided over a
dynamic binary interface to other PEIMs on a platform.
Tested with:
- SecurityPkg CI
- Verify RNG linked with RngLib is executed as expected
- Verify random numbers are generated successfully with a valid
RngLib
Integration instructions:
Use the `RngPei` module if a platform needs to produce
`gEfiRngPpiGuid`.
The platform should usually link a different `RngLib` instance to
`RngPei` than other PEIMs that may use the RNG PPI produced since
`RngPei` is responsible for producing the PPI.
For example, a `RngLib` instance that uses the rdrand instruction
may be linked against `RngPei` and a `RngLib` instance that uses
the RNG PPI may be linked against other PEIMs.
