In non blocking mode, the read function is expected
to return weather data is available for reading or not.
In case data are available but the size does not match
the expected size, the function read should return whatever
data is available.
Previously, the function was returning -1 with errno set
to EWOULDBLOCK even if the size of data in the buffer was
less than the requested size. It would only return the
available data if the size in the buffer was greater or equal
to the requested size.
The implementation of cdcacm_read is modified to return the avilable
data from the buffer even is the size is lesser than the requested
size.

fix(panic): fixed cache error being reported as illegal instruction
Closes IDF-6398, IDF-5657, IDF-7015, and IDF-6733
See merge request espressif/esp-idf!27430
On riscv chips accessing cache mapped memory regions over the ibus would
result in an illegal instructions exception triggering faster than the cache
error interrupt/exception.
Added a cache error check in the panic handler, if any cache errors are active
the panic handler will now report a cache error, even if the trigger exception
was a illegal instructions.
Similar to how the secondary init functions were already registered
via ESP_SYSTEM_INIT_FN, do the same for the core init functions.
This MR doesn't actually move the init functions into respective
components yet. This has to be carefully done in follow-up MRs.
Prior to this commit, if only critical_section.h is included, there
might be error about portNUM_PROCESSORS undeclared.
As critical_section.h should be OS-agnostic, added FreeRTOS.h in it
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.
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).
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.
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.
