Default timeout for interrupt WDT was increased by default
on ESP32, due to some heap integrity check APIs taking a long
time on large PSRAMs and causing timeouts.
But this adjustment was only done for ESP32, not later chips,
even though they may experience the same issue.
Adjusted to have the same behavior on all chips with PSRAM
enabled, making it consistant with the docs.

ESP_FAULT_ASSERT(C) was silently deleted by the optimizer when C is a cached
flag/status already proven by a preceding `if (!C) return/goto`: the compiler
folds C to a constant and drops all three checks, removing the fault-injection
protection with no warning.
This is a workaround for rom code issue, which can cause the chip to end in infinite loop
when reset is triggered from esptool/idf-monitor. This is only applicable to ESP32-C5 rev <= 1.0.

On RISC-V chips with SPIRAM support (esp32c5, esp32c61, esp32h4, esp32p4,
esp32s31), esp_restart_noos() was disabling the cache while the current
stack pointer could still be in external RAM. Any stack access after cache
disable (function call, local variable spill) would then fault with
"Cache disabled but cached memory region accessed".
Xtensa chips (esp32, esp32s2, esp32s3) already had this guard via the
SET_STACK macro. Add the equivalent for RISC-V:
- Add rv_utils_set_sp() to riscv/rv_utils.h (plain "mv sp, %0" with a
memory clobber; no window register management needed on RISC-V)
- In each affected system_internal.c, under
CONFIG_FREERTOS_TASK_CREATE_ALLOW_EXT_MEM, check whether the current
SP is in PSRAM and if so switch it to the top of internal BSS before
any cache disable or writeback operation
- Fix xTaskCreateStaticPinnedToCore() stack size argument in the
spiram_stack test (was passing bytes instead of word count)
- Mark the null-pointer write in func_do_exception() as volatile to
prevent the compiler from optimizing it away
- Extend the [spiram_stack] tests to RISC-V by sharing fibonacci() and
the task/finish helpers across architectures, guarding only the
Xtensa-specific WINDOWBASE/WINDOWSTART prints
If Task WDT is initialised but not start, the call to esp_timer_stop() in
the reconfigure path returns ESP_ERR_INVALID_STATE and reconfiguring the
Task WDT fails. This isn't the case when the Timer Group is used for Task
WDT.
(This failure cascades into the failure due to disabled interrupts, fixed
in the parent commit.)

- Failures were being masked as function always returned ESP_OK
- In the failure path the spinlock was not unlocked, so interrupts
became permanently disabled.

CMakev2's DEFERRED mode for idf_component_optional_requires only links
optional components already present in the dependency graph. This caused
esp_coex headers to be unavailable when building minimal examples on
targets with both WiFi and IEEE802154 (e.g. esp32c5, esp32c6).
Moving init_coexist to esp_coex removes the cross-component dependency
and ensures the init function is only compiled when esp_coex itself is
part of the build. A linker hook is added to guarantee the object file
is not silently discarded by the linker.
