build: determine toolchain tools dynamically

Since the introduction of the toolchain detection framework into the
build system, we have done determination and identification of the
toolchain(s) used for the build at the initialization of the build
system.

This incurs a large cost to the build every time - for every toolchain
that has been requested by the current makefile, we try to identify each
tool in the list of known tool classes, even if that tool doesn't
actually see any use.

For the clean and check-like targets we worked around this by disabling
most of the toolchains if we detect these targets, but this is
inflexible and not very reliable, and it still means that when building
normal targets we are incurring that cost for all tools whether they are
used or not.

This change instead modifies the toolchain detection framework to only
initialize a tool for a given toolchain when it is first used. This does
mean that we can no longer warn about an incorrectly-configured
toolchain at the beginning of build system invocation, but it has the
advantage of substantially reducing build time and the complexity of
*using* the framework (at the cost of an increase in complexity in the
framework itself).

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.

feat(simd): introduce simd context helper APIs

This patch adds the common API to save and restore FP and SVE. When SVE
is enabled we save and restore SVE which automatically covers FP. If FP
is enabled while SVE is not, then we save and restore FP only.

The patch uses simd_ctx_t to save and restore both FP and SVE which
means developers need not use fp or sve routines directly. Once all the
calls to fpregs_context_* are replaced with simd_ctx_*, we can remove
fp_regs_t data structure and macros (taken care in a following patch).

simd_ctx_t is currently allocated in section of its own. This will go
into BSS section by default but platform will have option of relocating
it to a different section by overriding in plat.ld.S.

build: consolidate directory creation rules

This commit streamlines directory creation by introducing a single
pattern rule to automatically make directories for which there is a
dependency.

We currently use several macros to generate rules to create directories
upon dependence, which is a significant amount of code and a lot of
redundancy. The rule introduced by this change represents a catch-all:
any rule dependency on a path ending in a forward slash is automatically
created.

Now, rules can rely on an unordered dependency (`|`) on `$$(@D)/` which,
when secondary expansion is enabled, expands to the directory of the
target being built, e.g.:

build/main.o: main.c | $$(@D)/ # automatically creates `build/`
