cpu: Allow storing an invalid HTM checkpoint

Commits 02745afd and f9b4e32 introduced a mechanism for creating checkpoint
objects for hardware transactional memory (HTM) and Arm TME. Because the
checkpoint object also contains the local UID of a transaction, it is
needed before any architectural checkpointing takes places. This caused
segfaults when running HTM codes.

This commit allows ISAs to allocate a checkpoint once at the beginning
of simulation.  In order to do that we need to remove the validity check
assertion; the cpt will become valid only after a first successfull
transaction start

mem: When loading an image directly in memory, use the right CL size.

Some code was added fairly recently which would load a memory image
into a memory directly in order to make it easier to set up ROMs.
Unfortunately, that code accidentally used the image size instead of
the cache line size when setting up the port proxy which would actually
write the data. This happens to work when the image size is a power of
two since that's all the proxy checks for, but there's no guarantee
that every image will be sized that way.

This change instead looks into the system object, retrieves the cache
line size from it, and uses that to set up the port proxy.

ext,tests: Copy test's output files from /tmp to testing-results

When a test is complete, the output files are in a random folder
in /tmp.

This commit adds a procedure copying those files to
testing-results/SuiteUID/TestUID/ folder, where SuiteUID and
TestUID are the corresponding uid's of the test.

This procedure is triggered after a test is complete and before
the folder in /tmp being removed.

ext: Force testlib to only create one Log object

Log object should remain being a singleton throughout the program.
The current code creates multiple Log objects, which at least
causes the issues of missing outputs in stdout.

E.g., "Logging call to command", which logs which command is

mem: Add NVM interface

Add NVM interface to memory controller.

This can be used with or instead of the existing
DRAM interface. Therefore, a single controller can interface
to either DRAM or NVM, or both.

Specifically, a memory channel can be configured as:
- Memory controller interfacing to DRAM only
- Memory controller interfacing to NVM only
- Memory controller interfacing to both DRAM and NVM

How data is placed or migrated between media types is outside
of the scope of this change.

The NVM interface incorporates new static delay parameters
for read and write completion. The interface defines a 2
stage read to manage non-deterministic read delays while
enabling deterministic data transfer, similar to NVDIMM-P.
The NVM interface also includes parameters to define
read and write buffers on the media side (on-DIMM). These are
utilized to quickly offload commands and write data, mitigating
the effects of lower latency and bandwidth media characteristics.

mem: Make MemCtrl a ClockedObject

Made DRAMCtrl a ClockedObject, with DRAMInterface
defined as an AbstractMemory. The address
ranges are now defined per interface. Currently
the model only includes a DRAMInterface but this
can be expanded for other media types.

The controller object includes a parameter to the
interface, which is setup when gem5 is configured.
