plat-k3: drivers: Refactor sec_proxy driver

Since the underneath transport layer may or may not always be sec_proxy
it doesn't make sense to keep following the k3_sec_proxy_* convention
for the TI_SCI message transports.
Rename them to something more generic like ti_sci_transport_*.

ci: notify_maintainers.py: filter out comment authors

This is a small bug fix for the notify_maintainers.py script which
should not mention a user who has already been involved in the
discussion. Currently, it filters out users that have explicitly been
mentioned (via '@user'), either by the CI bot or by a real user. But
it does not consider the comment authors. This is a mistake. Update
the code accordingly.

plat-k3: drivers: Open TRNG firewall for TIFS on all k3 devs

On k3 devices, TRNG is firewalled to be accessed only by OPTEE.

TIFS needs this for the encryption and decryption services to support
different low power modes. So, open firewall to TIFS as well.

There is no concurrent usage of TRNG, as TIFS uses TRNG only at suspend
when OPTEE is down and resume, when firewalls are restored but OPTEE is
not up yet.

As this is a firewall that required to be shared along with TIFS on all
devices, making this a common change and open on all devs.

compiler.h: detect builtin arithmetic overflow support with __has_builtin

Using the __has_builtin macro to check if the compiler has builtin
arithmetic overflow function. This makes OP-TEE use more efficient
code when compiled with clang.

Tested with clang 21.0.0 on arm64 platform, the generated assembly
is using the CPU flags to check overflow.

ci: free disk space earlier and in all jobs

Address two new "no space left on device" errors in CI:

- The first one appeared in the QEMUv8_checks_image_build job. To fix
it, avoid cloning the OP-TEE repository which is not needed in that job
i.e., remove the checkout action, and also run the host cleanup script.
The two other "image_build" jobs are updated as well for consistency.

- The second one happens in the _checks jobs. The fix consists in
running the host cleanup script earlier, before loading the Docker
image.
