Clean up linker script
...
This patch does the following:
- Add .text.* to the .text section in the output
- Add an assertion that the trampoline does not overflow a page
- Add the .rodata section
- Make .sdata and .sdata.* (which is for small data) be absorbed into
the .data section, because we don't need to distinguish between them;
this prevents .sdata from appearing in the output
- Make the analogous change for .srodata and .sbss
- Make all the data sections 16-byte aligned
This patch also updates the .editorconfig for *.ld files.
