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.
