SDL3, ImGUI, and OpenGL are unused dependencies. They will be enabled
once a GUI becomes necessary

Although this is mandated in the Barr C style guide, I find this
specific rule uneccesarry and tedious.

The linked list was implemented to store instructions in a basic block.
Instructions will now be stored in arrays to keep logic simple and
straight-foward.

Introduces IR instruction management, including instruction_t and
instruction_list_t definitions and their implementations. It also added
const-correctness to the value_t API.

Introduces jit/ir/value.h, which defines the value_t structure which is
a polymorphic container designed to hold various kinds of data that IR
instructions operate on or produce.

A new header, jit/a32_types.h, defines a32_register_t, an enum for Arm32
general purpose register's R0-R15, including standard aliases for SP,
LR, and PC.

This type is designed to hold various kinds of data that IR instructions
operate on, starting with immediate integer constants.

Introduces the core Arm32 decoder, including the instruction parsing
mechanism and an initial set of defined instructions.

Munmap can fail if the length argument is 0, and the address being freed
is not a multiple of the host's page size.

Strengthens the decoder's foundation but does not yet implement the core
instruction lookup table logic or the public arm32_decode API. These
will be addressed in future patches.

The term KVM is missleading because we are not using linux kernel
virtualization. PVM stands for "Pound Virtual Machine" which is more
accurate.

The mmio will not be touchwd for a couple months while we focus on
executing arm instructions. Once we get to that point this design doc
will be rewritten.

The changes affects multiple places in the repo and this one of the rare
instances where I cant be bothered writing a comprehensive commit. Look
at the diff for changes.
