feat(qemu): disable fpregs traps for QEMU in BL31

The BL31 boot process of QEMU requires, as a workaround, disabling of
fpregs trap in BL31. The fpregs trap is by default enabled and therefore
it needed to be explicitly disabled for the BL31 setup for QEMU.

build(handoff)!: switch to LibTL submodule

Removes in-tree Transfer List implementation and updates all references
to use the external LibTL submodule. Updates include paths, Makefile
macros, and platform integration logic to link with LibTL 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: LibTL 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.

refactor(qemu): guard handoff logic w/ build flag

Prepare for environments where the Firmware Handoff (LibTL)
submodule may not be available. Wrap all Transfer List dependent logic
in `#if TRANSFER_LIST` guards, ensuring QEMU can build and run without
the submodule.

This is useful for builds not integrating the firmware handoff
mechanism.

fix(qemu): fix variable may be used uninitialized error

When building with LTO, the compiler discovers that it is possible to
use the `ns_buf_base` variable without writing to it. This happens on
error by dt_add_ns_buf_node(). Check its return value and panic() if
something went wrong so the error doesn't propagate silently.

feat(cpufeat): enable FEAT_PAuth to FEAT_STATE_CHECKED

FEAT_PAuth is the second to last feature to be a boolean choice - it's
either unconditionally compiled in and must be present in hardware or
it's not compiled in. FEAT_PAuth is architected to be backwards
compatible - a subset of the branch guarding instructions (pacia/autia)
execute as NOPs when PAuth is not present. That subset is used with
`-mbranch-protection=standard` and -march pre-8.3. This patch adds the
necessary logic to also check accesses of the non-backward compatible
registers and allow a fully checked implementation.

Note that a checked support requires -march to be pre 8.3, as otherwise
the compiler will include branch protection instructions that are not
NOPs without PAuth (eg retaa) which cannot be checked.

refactor(cpus): register DSU errata with the errata framework's wrappers

The existing DSU errata workarounds hijack the errata framework's inner
workings to register with it. However, that is undesirable as any change
to the framework may end up missing these workarounds. So convert the
checks and workarounds to macros and have them included with the
standard wrappers.

The only problem with this is the is_scu_present_in_dsu weak function.
Fortunately, it is only needed for 2 of the errata and only on 3 cores.
So drop it, assuming the default behaviour and have the callers handle
the exception.

fix(qemu): statically allocate bitlocks array

gpt_runtime_init() now takes the bitlock array's address and size as
argument. Rather than reserving space at the end of the L0 GPT for
storing bitlocks, allocate a static array and pass its address to
gpt_runtime_init(). This frees up a little bit of space formerly
reserved for alignment of the GPT.
