0bac33ed41 esp_system: Remove deprecate section from esp_cpu.h
- 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.

6005cc9163 hal: Deprecate interrupt_controller_hal.h, cpu_hal.h and cpu_ll.h interfaces
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.

64117a0c59 esp_system: Fix esp_cpu_compare_and_set()
This commit fixes esp_cpu_compare_and_set() in the following ways

- Removed call to esp_ptr_external_ram() as it incurred > 80 CPU cycles (due to multiple nested
  function calls, and those functions not being in IRAM). We now check manually if the pointer
  is in external RAM for increased speed.
- Fixed infinite wait when attempting to get the external_ram_cas_lock. The function should
  return immediatley if any part of the compare and set call fails.
- The preprocessor conditions of esp_cpu_compare_and_set() to depend on CONFIG_SPIRAM instead
  of SOC_SPIRAM_SUPPORTED. Even if the target supports SPIRAM, we only need the external RAM
  compare and set feature if SPIRAM is enabled.

Also fixed incorrect inclusion of esp_intr_alloc.h in esp_cpu.h

61eb7baa6b esp_hw_support: Add esp_cpu.h abstraction and API
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

e22b4007d3 esp_hw_support: Removed deprecated CPU util functions
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h

The following functions are deprecated:
- get_sp()

The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()

The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()

All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.
