This does two things so I'll split them.
(1) Add function intern_constant() which adds a constant to the
constants array and returns the index.
The assembly for this function is beautiful. Only one load and store on
a successfull path.
Dump of assembler code for function intern_constant:

0x0000000000010ee4 <+4>: cbnz w8, 0x10f08 <intern_constant+40>

End of assembler dump.
(2) I've decided that the entire translation code will fit in
bal_engine.c so the bal_ir_immiter and bal_translator files are not
needed anymore. I moved their preprocessor definitions into bal_engine.c

Windows does not support the doc target, which causes the CI to fail.
Marking the doc target as ALL should fix this.

While I do not like the Rust Language as a whole, their documentation
generator is the best I've ever seen. in any language. I want to
implement something like it for Ballistic.
Like I said in the README, I have absolutely zero motivation to create
a documentation generator so `cdoc.c` is made completely with AI. The
code is messy but the generated HTML files look beautiful.

Everything has been setup except for the main translation loop which
have to be done another day. Its after midnight for me right now :(

The decoder API is now suitable to be made public. decoder.h is the sole
entry point for the decoder and it has been moved to `include/`

This program takes a 32-bit hexidecimal representing an ARM instruction
and prints its corresponding mnemonic. This program will be used in
tandem with a python fuzzing script to verify the decoder table
generated by tools/generate_a64_table.py.

Apperantly -Wall does exactly what it says it does on Windows and enables
every single warning. This is why the build fails on Windows and not on
Linux or MacOS.

This is just to test if the decoder even works. Ii will implement a
fuzzer to test the decoder against 10,000 randomly generated
instructions.

Adds a python script, tools/generate_a64_table.py, to parse ARM's
machine readable XML. The script generates a static C lookup table
containing instruction mnemonics, masks, and values.
