fix(fvp): enable FEAT_MTE2

ENABLE_FEAT_MTE2 controls the trapping of some MTE related system
registers. If the memory_tagging_support_level parameter on the FVP
command line is set to higher values, non-secure world will see the
feature bits in the CPU ID registers and will use those registers,
triggering a panic in BL31.

Enable the feature in the optional form for the FVP build, to avoid any
panics.

fix(arm): add extra hash config to validate ROTPK

The default mbedTLS configuration enables hash algorithms based on
the HASH_ALG or MBOOT_EL_HASH_ALG selected. However, the Arm ROTPK
is always embedded as a SHA256 hash in BL1 and BL2. In the future,
we may need to adjust this to use the HASH_ALG algorithm for
embedding the ROTPK hash.

As a temporary workaround, a separate mbedTLS configuration has
been created for Arm platforms to explicitly set SHA256 defines,
rather than relying on the default configuration. This adjustment
is reflected in the mbedTLS configuration file for the TC platform
as well as in the PSA Crypto configuration file.

feat(tc): enable SME and SME2 options for TC4

Set the Make flags for TF-A to be able to enable SME and SME2 features.
Note that we enable these architectural features for both the secure and
non-secure worlds, which is required on TC4.

In the case of the non-secure world, we specify a value of 2 for the
flag which specifies that TF-A should check the feature register to
ensure that the feature is present before enabling it. This allows these
flags to be compatible with all platforms and stops TF-A doing anything
different if it does not detect that the feature is present.

fix(cot-dt2c): fix various breakages

This change fixes several breakages that were introduced in some build
configurations by the introduction of the cot-dt2c tool.

Some Python environments cannot be managed directly via `pip`, and
invocations of `make`, including `make distclean`, would cause errors
along the lines of:

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

This change has been resolved by ensuring that calls to the cot-dt2c
tool from the build system happen exclusively through Poetry, which
automatically sets up a virtual environment that *can* be modified.

Some environments saw the following error when building platforms where
the cot-dt2c tool was used:

make: *** No rule to make target '<..>/debug/bl2_cot.c', needed
by '<..>/debug/bl2/bl2_cot.o'. Stop.

Additionally, environments with a more recent version of Python saw the
following error:

File "<...>/lib/python3.12/site-packages/cot_dt2c/cot_parser.py",
line 637, in img_to_c
if ifdef:
^^^^^
NameError: name 'ifdef' is not defined

Both of these errors have now been resolved by modifications to the
build system and the cot-dt2c tool to enable preprocessing of the device
tree source file before it is processed by the tool.

As a consequence of this change, the `pydevicetree` library is no longer
vendored into the repository tree, and we instead pull it in via a
dependency in Poetry.

This change also resolves several MyPy warnings and errors related to
missing type hints.

refactor(cm): remove el1 context when SPMD_SPM_AT_SEL2=1

* Currently, EL1 context is included in cpu_context_t by default
for all the build configurations.
As part of the cpu context structure, we hold a copy of EL1, EL2
system registers, per world per PE. This context structure is
enormous and will continue to grow bigger with the addition of
new features incorporating new registers.

* Ideally, EL3 should save and restore the system registers at its next
lower exception level, which is EL2 in majority of the configurations.

* This patch aims at optimising the memory allocation in cases, when
the members from the context structure are unused. So el1 system
register context must be omitted when lower EL is always x-EL2.

* "CTX_INCLUDE_EL2_REGS" is the internal build flag which gets set,
when SPD=spmd and SPMD_SPM_AT_SEL2=1 or ENABLE_RME=1.
It indicates, the system registers at EL2 are context switched for
the respective build configuration. Here, there is no need to save
and restore EL1 system registers, while x-EL2 is enabled.

Henceforth, this patch addresses this issue, by taking out the EL1
context at all possible places, while EL2 (CTX_INCLUDE_EL2_REGS) is
enabled, there by saving memory.
