If the TimerGroup 0 clock is disabled and then reenabled, the watchdog
registers (Flashboot protection included) will be re-enabled, and some
seconds later, will trigger an unintended reset.

ESP32-C2 has a single group timer, thus it will use it for the interrupt watchdog,
which is more critical than the task watchdog. The latter is implement in
software thanks to the `esp_timer`component.
This commit removes the riscv_interrupts.h header is it has become redundant. The previously
exposed API has been handled as follows:
- "riscv_interrupt_enable()" and "riscv_interrupt_disable()" have been removed. These functions
were declarations only and never had any implementation.
- "riscv_global_interrupts_enable()" and "riscv_global_interrupts_disable()" renamed to
"rv_utils_intr_global_enable()" and "rv_utils_intr_global_disable()" respectively and now
placed in rv_utils.h
For RISC-V and Xtensa targets, in case a panic needs to happen when
Task WDT is triggered (ESP_TASK_WDT_PANIC), the interruptee's stack
is now used for printing the backtrace.
Abort after Task Watchdog is triggered can happen on APP CPU (second core).
Functions used for burning this efuse would log, but at this point
esp_log is not initialized. Moved to a later point in the startup process.

Blocking read from cdcacm VFS could return less bytes than requested.
This didn’t match the behaviour of other VFS drivers, and higher level
code could misbehave.
Previously, reset over USB CDC was done by calling esp_restart from
an interrupt handler. This works only until some restart hook function
is registered using esp_register_shutdown_handler, and the hook
function tries to do something that isn’t allowed in an interrupt
handler. One such case is with Wi-Fi. When Wi-Fi driver is installed,
it registers esp_wifi_stop as a shutdown handler function. However
esp_wifi_stop cannot be called from an ISR, and hence we shouldn’t
call esp_restart from an ISR either.
This commit modifies USB CDC driver to call esp_restart by posting it
to esp_timer task.

Spinlocks themselves do not constitute critical sections as after a spinlock is acquired, interrupts
can remain enabled. However, there are some places where spinlocks are used direclty instead of using
the portMUX_TYPE and portENTER_CRITICAL_...() APIs. This commit fixes those calls.
- Remove esp_cpu_in_ocd_mode() from esp_cpu.h. Users should call esp_cpu_dbgr_is_attached() instead.
- Remove esp_cpu_get_ccount() from esp_cpu.h. Users should call esp_cpu_get_cycle_count() instead.
- Remove esp_cpu_set_ccount() from esp_cpu.h. Users should call esp_cpu_set_cycle_count() instead.
- Other IDF components updated to call esp_cpu_dbgr_is_attached(), esp_cpu_get_cycle_count() and esp_cpu_set_cycle_count() as well.
This commit marks all functions in interrupt_controller_hal.h, cpu_ll.h and cpu_hal.h as deprecated.
Users should use functions from esp_cpu.h instead.
The following two functions in bootloader_support are private now:
* esp_secure_boot_verify_sbv2_signature_block()
* esp_secure_boot_verify_rsa_signature_block()
They have been moved into private header files
inside bootloader_private/
* Removed bootloader_reset_reason.h and
bootloader_common_get_reset_reason() completely.
Alternative in ROM component is available.
* made esp_efuse.h independent of target-specific rom header
1. Rename MACROs SYSTEM_WIFI_RST_EN register bit fields to be more recognizable
2. reset Bluetooth baseband and clock bits to fix the issue of task watchdog triggered during controller initialization due to invalid hardware state
SMP FreeRTOS uses a single kernel lock for all critical sections. There is a known
issue with esp_ipc_isr_stall_other_cpu() that can cause dead if the other CPU is
already in a critical section.
This commit adds a temporary workaround to reduce the chance of deadlock by taking
the SMP FreeRTOS kernel lock first before stalling the other CPU.
See IDF-5257 for more details.
