drivers: gpio: add configure functions

Align the OP-TEE GPIO driver with GPIO lib (devm_gpiod_get_index with
enum gpiod_flags) and add a way to select the GPIO configuration directly
during request with the new function, gpio_dt_cfg_by_index().

This patch remove assumption on GPIO direction (gpio input was assumed in
GPIO driver) or output level when the GPIO is requested by consumer.
with this patch it must be requested explicitly with:
- GPIO_IN: configure the input GPIO
- GPIO_ASIS: direction is managed by caller later with gpio_set_value()
call.
- GPIO_OUT_LOW / GPIO_OUT_HIGH: output GPIO at expected level,
the sequence for GPIO have the correct order to avoid glitch by using
the gpio function at the correct order.

This patch is a preliminary step for the introduction of ops configure.
The API gpio_dt_get_by_index() is keep for backward compatibility but
should be used with gpio_configure() or replaced by gpio_dt_cfg_by_index().

Now gpio_configure() is only used in the 2 drivers, regulator_fixed and
regulator_gpio, because in these drivers the flags gpio->dt_flags are
modified after call of gpio_dt_get_by_index().

For get_voltage_level_gpio(), GPIO_OUT_HIGH is used by default as it is
done in Linux function of_get_gpio_regulator_config().

core: add ASan runtime tests to core self-tests

Adds a set of AddressSanitizer (ASan) runtime tests.
Covers stack overflow, global buffer overflow, heap overflow,
use-after-free, invalid memcpy/memset cases.

These tests are important to ensure that ASan works correctly
when enabled. Implementation of functions such as memset() and memcpy()
may change in the future, or ASan support may silently break when
switching to a new compiler version. Having explicit tests provides
confidence that ASan instrumentation remains functional and correctly
detects memory errors.

convention.
- Replace the custom base64 implementation with the base64 library
added in PR OP-TEE#7007.
- Update QCBOR integration by removing custom QCBOR files and using
the standard library, adjusting paths as necessary.
- Apply region validation improvements introduced in PR OP-TEE#6195.
- Update API calls in sign.c to align with libmbedtls changes from
PR OP-TEE#6151.
- Calculate the required buffer size at runtime to minimize memory
allocation.
- Refactor code to improve readability and maintainability.

core: add flag to enumerate TAs when secure storage is ready

Add TA_FLAG_DEVICE_ENUM_TEE_STORAGE_PRIVATE with similar usage as
TA_FLAG_DEVICE_ENUM_SUPP except that it is used to add an enumeration
point when secure storage is ready.

The new TA function PTA_CMD_GET_DEVICES_RPMB is added to the device PTA
to report TAs depending on RPMB.

PTA_CMD_GET_DEVICES_RPMB will if CFG_REE_FS!=y and CFG_RPMB_FS=y first
try to initialize RPMB and only if successful will it return eventual
TAs with the TA_FLAG_DEVICE_ENUM_TEE_STORAGE_PRIVATE flag set.

PTA_CMD_GET_DEVICES_SUPP will if CFG_REE_FS=y include TAs with the
TA_FLAG_DEVICE_ENUM_TEE_STORAGE_PRIVATE flag set in the list of TAs to
return.
