Older versions of GenFw put the wrong value in the debug directory size
field in the PE/COFF header: instead of putting the combined size of all
the entries, it puts the size of the only entry it creates, but adds the
size of the NB10 payload that the entry points to. This confuses the
loader now that we started using additional debug directory entries to
describe DLL characteristics.
GenFw was fixed in commit 60e85a39fe, but the binaries that were
generated with it still need to be supported.
So let's detect this condition, and check whether the size of the debug
directory is consistent with the NB10 payload: if we should expect
additional directory entries where we observe the NB10 payload, the size
field is clearly wrong, and we can break from the loop.

Currently, the AArch64 implementation of LongJump() avoids using the RET
instruction to perform the jump, even though the target address is held
in the link register X30, as the nature of a long jump implies that the
ordinary return address prediction machinery will not be able to make a
correct prediction.
However, LongJump() is rarely used, and the return stack will be out of
sync in any case, so this optimization has little value in practice, and
given that indirect calls other than function returns require a BTI
landing pad at the call site, this optimization is not compatible with
BTI. So let's just use RET instead.

RegisterCpuInterruptHandler did not allow setting
exception handlers for anything beyond the timer IRQ.
Beyond that, it didn't meet the spec around handling
of inputs.
RiscVSupervisorModeTrapHandler now will invoke
set handlers for both exceptions and interrupts.
Two arrays of handlers are maintained - one for exceptions
and one for interrupts.
For unhandled traps, RiscVSupervisorModeTrapHandler dumps
state using the now implemented DumpCpuContext.
For EFI_SYSTEM_CONTEXT_RISCV64, extend this with the trapped
PC address (SEPC), just like on AArch64 (ELR). This is
necessary for X86EmulatorPkg to work as it allows a trap
handler to return execution to a different place. Add
SSTATUS/STVAL as well, at least for debugging purposes. There
is no value in hiding this.
Fix nested exception handling. Handler code should not
be saving SIE (the value is saved in SSTATUS.SPIE) or
directly restored (that's done by SRET). Save and
restore the entire SSTATUS and STVAL, too.
