YAMAMOTO Takashi e596d5bd5e binfmt/libelf: Implement sh_addralign handling 
Basically, mirror the following two commits from modlib.
It's shame we have two copies of elf loaders.

    modlib: Implement sh_addralign handling

    I've seen a module with 16 bytes .rodata alignment for xmm operations.
    It was getting SEGV on sim/Linux because of the alignment issue.
    The same module binary seems working fine after applying this patch.

    Also, tested on sim/macOS and esp32 on qemu,
    using a module with an artificially large alignment. (64 bytes)
```

    modlib: Always use separate allocation for text and data

    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
