Is your feature request related to a problem? Please describe.
Currently, each module's version select are done based on predefined macro in ( core-isa.h), which is not able to be configurable.
code list below, take volume as example:

#if defined(__XCC__)
# include <xtensa/config/core-isa.h>
# if XCHAL_HAVE_HIFI4
#  define VOLUME_HIFI4
# elif XCHAL_HAVE_HIFI3
#  define VOLUME_HIFI3
# else
#  define VOLUME_GENERIC
# endif
#else
# define VOLUME_GENERIC
#endif

Describe the solution you'd like
Prefer use Kconfig to provide a choice for developer, then module version can be changed in a unified way.

Describe alternatives you've considered
There are multiple ways to resolve this request:

1. add -C=-DCONFIG_VOLUME_HIFI3=y or similar to build cmd line to provide switch for volume hifi3/hifi4/generic.
   pros: nothing need change.
   cons: if want to switch with multiple modules, cmd line would be much longer and not easy to know which are take effect and which not.

2. current implement in PR: Volume: Add volume SIMD build option #8682
   pros: it achieved configurable and remove select code in header file(listed above).
   cons: add a new build env and need align with test bench build.
   personally, I still think this is the good way, it removed #if in each module header, and configurable for module also done.

3. provide choice make generic as default and set HIFI version in each platform Kconfig
   pros: implementation is simple.
   cons:
   1. As kai mentioned, there are cloud build for mtl, and no xtensa tool chain, which will cause build error.
   2. need address each platform to add correct HIFI version kconfig.

4. provide choice and make a DUMMY(name can be discussed, just use it as default choice), keep current header selection.
   pros: this is a very simple implementation, without any break and can achieve module customization.
   cons: still need header above code support to get the real default HIFI version, this is a mediate solution.

Please address your comments here and we need finalize which solution is best for now.
