feat(build): check that .text section starts at page boundary

Linker may decide to put new unspecified sections before .text
section. That will cause non-working image, because entry point isn't
at __BLXX_START__. Device just not booted with such image.

This happened for example with .note.gnu.build-id section generated
for LTO build in some cases. Now linker will report this situation as
an error.

```
/usr/lib/gcc-cross/aarch64-linux-gnu/13/../../../../aarch64-linux-gnu/bin/ld: .text is not aligned on a page boundary.
collect2: error: ld returned 1 exit status
```
