feat(cpus): add support for Neoverse-N2 prefetcher

To get accurate and repeatable L2 cache performance metrics,
the L2 region prefetcher must be disabled. This prevents
speculative fetches from interfering with the measurements.

This patch adds a build-time option, NEOVERSE_N2_PREFETCHER_DISABLE,
to set the PF_DIS bit (bit 15) in the CPUECTLR_EL1 register for this
purpose.

fix(build): don't rely on Event Log build tree

Follow proper CMake usage by installing libeventlog and referring to
the installed artifacts rather than the build directory. The previous
approach relied on build-tree paths, which is considered an anti-
pattern and may break across CMake versions since the build layout is
not stable or part of the public interface.

This change installs libeventlog into a staging directory and updates
the TF-A build to use the installed include and library paths. This
improves portability, stability, and compliance with CMake idioms.

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.

fix(build): scan symbols until all are resolved

This small change ensures that unresolved references between object
files are resolved regardless of the order that they are provided to the
linker. This is beneficial for us, because it allows us to append
libraries to variables like `BLx_LIBS` without concern for ordering.

No update is necessary for armlink, which already implements this
behaviour by default.

fix(build): fix compiler wrapper detection

A late change in the recently-merged compiler wrapper detection change
stack introduced two issues:

Firstly, the `irange` function - a dependency of the compiler wrapper
detection implementation - was taken out of the change stack, which
meant uses of it evaluated to empty.

Secondly, the shell command used by the `shell-slice` function was
replaced with an alternative implementation which incorrectly sliced the
shell words inclusively rather than exclusively.

This change resolves the issues caused by these changes by replacing the
use of the `irange` function with `shell-map`, and by ensuring that the
`shell-slice` function correctly uses an exclusive end value.

fix(st-clock): prevent panic when external oscillator is absent

To deactivate the external oscillator, the frequency must be set to 0
in the device tree.
The frequency check for 0 was implemented in clk_stm32_osc_gate_enable()
and clk_stm32_osc_gate_disable(), but missing in
clk_stm32_osc_gate_is_enabled().
Since clk_stm32_osc_gate_is_enabled() is called by clk_enable()
to verify if the clock is actually enabled, this fix prevents a panic
when the oscillator is not present.
