The digest length and the condition that reserves it at the end of RTC RAM were
duplicated in seven places. Hold the reservation in a hidden Kconfig value that
is zero when the feature does not apply, so every consumer subtracts it
unconditionally, and derive ESP_SECURE_BOOT_DIGEST_LEN from it.
After startup is done and app_main is reached, all calls to
heap_caps_add_region_with_caps (adding a new heap to the list of registered
heaps) will not affect the minimum free heap size value.
For heaps created before startup, this won't apply and their size will
end up being taken into account in the calculation of the minimum.
Adds CONFIG_SPIRAM_ENC_EXEMPT, available on chips that support per-page
PSRAM encryption configuration (esp32c5, esp32c61, esp32p4). When
enabled, esp_psram carves CONFIG_SPIRAM_ENC_EXEMPT_SIZE off the top of
PSRAM and maps it via the new mmu_hal_map_region_no_enc() helper, which
writes MMU entries without the SENSITIVE bit. The region is registered
as a separate heap pool reachable only through the new
MALLOC_CAP_SPIRAM_NO_ENC capability bit, so default SPIRAM allocations
cannot accidentally land there.
PSRAM encryption imposes alignment constraints that some DMA engines
(e.g. 2D-DMA) cannot satisfy. This option lets such workloads place
their buffers in unencrypted PSRAM while keeping the rest of PSRAM
(and flash) encrypted. Default disabled; security implications are
documented in the Kconfig help text.
Fixed compilation error when building with -Wwrite-strings or
-Wdiscarded-qualifiers by adding const qualifier to char pointers with
string literals.

IDF_BUILD_V2 does not have BUILD_COMPONENTS build property. Therefore,
when IDF_BUILD_V2 is defined, use a generator expressions instead. I
believe that the one-liner should also work with IDF_BUILD_V1, but the
change is kept separate to clearly show the difference between
IDF_BUILD_V1 and IDF_BUILD_V2.

Add a condition on the definition of the MALLOC_CAP_EXEC macro to
prevent it from being defined if ESP_SYSTEM_MEMPROT_FEATURE or
ESP_SYSTEM_PMP_IDRAM_SPLIT is enabled, thus throwing a compile time
error when using it.

The following updates have been made in this commit:
- The commit places FreeRTOS code in flash memory by default.
- CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH has been removed.
- CONFIG_FREERTOS_IN_IRAM is unhidden and can be used to restore the
previous memory placement.
- A test has been added for users to conduct performance impact testing
based on memory placement configurations.
