This allows us to remove duplicated code previously used to obtain the partition ID.

Therefore, treat the EFI_UNSUPPORTED error returned during Rx/Tx buffer mapping as a valid result when the ARM_FFA_PARTITION_INFO_GET_REGS ABI is supported.

This ABI is useful in environments where the Rx/Tx buffer does not need to be mapped, or where buffer mapping is not supported for retrieving partition information. To support this, two new APIs are introduced: ArmFfaLibPartitionInfoGetRegs() and ArmFfaLibPartitionCountGetRegs().

This change adds the FFA_YIELD handling from ArmFfaLib to support long operations from secure partitions. Timeout arguments are ignored because systems in this context cannot benefit from the timeout period. Treating FFA_YIELD like FFA_INTERRUPT and expecting the caller to invoke FFA_RUN is the least disruptive approach while achieving the intended behavior. This was tested on proprietary hardware platforms and booted to Windows.

This makes a failure of loading StandaloneMm in legacy platform which doesn't implements Rx/Tx buffer related API since it doesn't need to. StandaloneMm could be only service provider not cosumer in some platform where doesn't need to map RxTx buffer. Therefore, Considier EFI_UNSUPPORTED return in ArmFfaStandaloneMmLib's constructor.

However, since ArmFfaLibRun() gets its return in its stack variable, So caller of ArmFfaLibRun() doesn't get the return arguments from secure partition. To resolve this, add output parameter to ArmFfaLibRun() to receive return arguments.
