Add configurables section offset in the preamble (#6522)

The preamble now contains 8 bytes of offset to the configurables
section. If there is no configurable const in the data-section, then the
value of this integer will be equal to the size of the binary itself.

This also means that we now sort the data-section to have all the
non-configurables first, and then the configurables.

The preamble final asm looks like this (the offset to configurables is
0'd out here in the example):
```
;; ASM: Final program
;; Program kind: Script
.program:
move $$tmp $pc
jmpf $zero i10
DATA_SECTION_OFFSET[0..32]
DATA_SECTION_OFFSET[32..64]
CONFIGURABLES_OFFSET[0..32]
CONFIGURABLES_OFFSET[32..64]
lw   $$ds $$tmp i1
add  $$ds $$ds $$tmp
```
The preamble bytecode looks like this:

```
0x00000000 MOVE R60 $pc                                    ;; [26, 240, 48, 0]
0x00000004 JMPF $zero 0xa                                  ;; [116, 0, 0, 10]
0x00000008                                                 ;; [0, 0, 0, 0, 0, 0, 2, 40]
0x00000010                                                 ;; [0, 0, 0, 0, 0, 0, 0, 0]
0x00000030 LW R63 R60 0x1                                  ;; [93, 255, 192, 1]
0x00000034 ADD R63 R63 R60                                 ;; [16, 255, 255, 0]
...
```
