refactor(rpi3): use crypto-agile measured boot

Adopt the crypto-agile measured boot API for RPi3. Replace the previous
single-algorithm hash configuration with dynamic algorithm selection.
Factor common measurement logic into a shared helper, update BL1/BL2
integration, and ensure event log header generation and TPM extension
use the new multi-algorithm model.

feat(tpm): changes to support TPM lib

The build system sets TPM_INTERFACE to FIFO_SPI, but this cannot be
tested by the C preprocessor. So, create new build define
TPM_INTERFACE_FIFO_SPI. Correct the #if statements to use it.

Make spi_init() in rpi3_spi.c static.
Pass timer functions as ops structure to TPM.
Remove implicit interface between TPM library and main firmware by
introducing explicit interface to allow firmware to pass structure
of function pointers to setup a timer and check whether it has elapsed.

Update build system for new TPM lib location.
Change #include statements in TPM source and header files to allow
for new directory structure.

fix(build): link Event Log library directly

The `libraries` target is a `.PHONY` target to which various real
library targets, including the Event Log library, have been added over
the years. This target is added as a dependency to any target created
with the `MAKE_BL` function. While this might look convenient on the
surface, it also dictates that a library must be linked even to images
it is totally irrelevant for.

The Event Log library is a good example of this; the library is not
typically used by all images, but by attaching itself to the `libraries`
target it becomes mandatory for all of them.

This change returns some of the control over when and where the Event
Log goes to platform maintainers via the introduction of two new
variables:

- `LIBEVLOG_LIBS`: the path to the Event Log static library.
- `LIBEVLOG_INCLUDE_DIRS`: include directories for the public API.

These can be appended to `BLx_LIBS` and `BLx_INCLUDE_DIRS` to include
the Event Log library in the relevant bootloaders.

chore(libfdt): update libfdt to v1.7.2

Where previously we cherry-picked individual sources from the libfdt
project tree, this change instead integrates the entire project tree
into the TF-A repository. Doing so reduces the manual overhead of
updating libfdt in the future, as we avoid the need to analyse
individual source-level dependencies.

libfdt, conveniently, also provides a Makefile designed to ease its
integration into foreign build systems (like TF-A's), which we also make
use of in this change.

build(measured-boot)!: move to ext event log lib

Removes in-tree Event Log library implementation and updates all
references to use the external submodule. Updates include paths,
Makefile macros, and platform integration logic to link with lib as a
static library.

If you cloned TF-A without the `--recurse-submodules` flag, you can
ensure that this submodule is present by running:

git submodule update --init --recursive

BREAKING-CHANGE: LibEventLog is now included in TF-A as a submodule.
Please run `git submodule update --init --recursive` if you encounter
issues after migrating to the latest version of TF-A.

The platform utilizes the gpio_spi.c driver to bit-bang gpio pins in
order to send commands and receive responses to/from the TPM.
In BL1 & BL2:
-utilize TPM commands to initialize the gpio pins for "spi"
communication, and extend image hashes to the TPM's PCR 0,
at the end of the measured boot phase for the bootloader,
the TPM locality is released.
-Bl1 executes a tpm_startup command in order to flush the TPM.
