Updated kconfig option type and other supporting changes in build system
to allow enabling both ULP FSM and ULP RISCV simultaneously. Users can
choose at run time which one to initialize and use.
NOTE: Both ULP FSM and ULP RISCV can't be used simultaneously at run
time because they share some common hardware like RTC slow memory space.
Closes https://github.com/espressif/esp-idf/issues/12999
The ULP sources include sdkconfig.h for compile-time configuration
values. The sdkconfig directory was previously available to the ULP
target indirectly through the COMPONENT_INCLUDES variable, which is
populated from the parent component's INTERFACE_INCLUDE_DIRECTORIES.
In cmake v1, idf_component_register() adds the config_dir as PUBLIC
include directory to every component (component.cmake:498), so it
ends up in INTERFACE_INCLUDE_DIRECTORIES and gets passed to the ULP
subproject via COMPONENT_INCLUDES.
In cmakev2, the config_dir is added as a build-level property and
applied to components as PRIVATE (component.cmake:1053), so it no
longer appears in INTERFACE_INCLUDE_DIRECTORIES. As a result, the
sdkconfig directory is missing from the ULP target's include paths.
Add the sdkconfig directory explicitly to the ULP target's include
directories. Note that SDKCONFIG_HEADER is already passed to the ULP
subproject and its directory is already extracted into sdkconfig_dir
for linker script preprocessing (IDFULPProject.cmake:40).

This commit:
- Removes the link time symbol name clash detection.
- Extracts symbols of type NOTYPE for global identifiers defined in
assembly files.
- Makes the prefix argument optional for ulp_add_build_binary_targets().
- Adds a unit test for the ulp binary embed with a prefix feature.
This commit adds APIs to initialize and configure the LP ADC from the HP
core and also adds APIs to read the raw and converted ADC values from the LP core.
