- add hardware stack guard based on assist-debug module
- enable hardware stack guard by default
- disable hardware stack guard for freertos ci.release test
- refactor rtos_int_enter/rtos_int_exit to change SP register inside them
- fix panic_reason.h header for RISC-V
- update docs to include information about the new feature
Changed rv_utils_intr_edge_ack and esp_cpu_intr_edge_ack to
take uint32_t instead of int to avoid build errors.
The test is to test in particular that __builtin_ffsll, used in
xt_utils.h, which is included via esp_cpu.h, compiles fine
in C++20 with -Wsign-conversion enabled.

This commit fixes the function declaration naming from esprv_intc_set_threshold()
to esprv_intc_int_set_threshold(), thus allowing the underlying ROM funciton to be
exposed via the header.
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
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 updates the esp_cpu.h API. The new API presents a new
abstraction of the CPU where CPU presents the following interfaces:
- CPU Control (to stall/unstall/reset the CPU)
- CPU Registers (to read registers commonly used in SW such as SP, PC)
- CPU Interrupts (to inquire/allocate/control the CPUs 32 interrupts)
- Memory Port (to configure the CPU's memory bus for memory protection)
- Debugging (to configure/control the CPU's debugging port)
Note: Also added FORCE_INLINE_ATTR to the DoxyFile in order to pass doc
builds for esp_cpu.h
After refactoring the target components (e.g. esp32) no longer contained any real functionality.
What remained in these components have been moved elsewhere and the component itself deleted from the
build system.
Enable shared stack watchpoint for overflow detection
Enable unit tests:
* "test printf using shared buffer stack" for C3
* "Test vTaskDelayUntil" for S2
* "UART can do poll()" for C3
Software support for PMS module.
Allows controlled memory access to IRAM (R/W/X) and DRAM0 (R/W)
On/locked by default, configurable in Kconfig (esp_system)

The riscv vectors.S in riscv component contains the trap vector, which is responsible to
defer interrupts and examine if a task context switch is needed, this change cleans up
this code by hiding all freertos details behind on two functions rtos_it_enter/exit and
their implementations are placed in freertos riscv port files.
SoC level exceptions such as watchdog timer and cache errors are now supported.
Such exceptions now triggers a panic, giving more information about how
and when it happened.
