e5155c2a54 fix(riscv): fix a bug in FPU exception handling
On the ESP32-P4, it is possible to have an exception because of an FPU instruction
while EXT_ILL CSR is not zero and its FPU bit is not set.

a8b1475fe7 feat(riscv): implement coprocessors save area and FPU support
This commit mainly targets the ESP32-P4. It adds supports for coprocessors on
RISC-V based targets. The coprocessor save area, describing the used coprocessors
is stored at the end of the stack of each task (highest address) whereas each
coprocessor save area is allocated at the beginning of the task (lowest address).
The context of each coprocessor is saved lazily, by the task that want to use it.

4df3ff619e feat(esp_system): implement hw stack guard for riscv chips
- 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

53c7dd4efc WDT: implement interrupt wdt and task wdt for ESP32-C2
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.

220e52fca1 RISC-V: Fix vectors.S assembly file indentation and macro usage
The file is now more consistent as the macros have been fixed, more comments
have been added and the indentation is now using spaces only.

810be86f21 freertos/riscv: move freertos aware interrupt code from vectors to the freertos riscv port.
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.

b6a450f824 panic: Add support for SoC-level panic
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.
