modlib: Always use separate allocation for text and data

Browse Source 
Pros:

* Reduce code differences
* Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT

Cons:

* Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total

Tested with:

* sim:module on macOS
* esp32-devkit:nsh + CONFIG_MODULE on qemu
* lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu
