bal_memory_destroy_flat() frees heap allocated memory AND resets
`interface` to 0, which the docs do not specify.

Code coverage tools cannot fully cover BAL_LOG_* statements because of
the numerous if statements in BAL_LOG(). We extract the code in
BAL_LOG() to bal_log_message() to fix this issue.

Adds BAL_LOG_LEVEL_NONE to to the bal_log_level_t enum. This gives users
the option to disable logging completely if BAL_LOG_LEVEL_NONE is set as
the mininum log level.

This enum is very useful for the translation loop and including the
entirety of bal_assembler.h just to get it is not a good idea. This enum
has been moved to bal_types.h.

I truly dont if markdown code examples peoduce warnings, but those
warnings cannot make the build fail to compile.

In the ADD Extended Register encoding, bitfield "option" Bit[13:15] was
not being detected by the python script. This commit parses this
bitfield correctly. Consequently, the size of the operands array has to
be raised from 4 to 5 to support this new operand.

I recently got a new PC with Jetbrain's Clion IDE and this commit fixes
warnings generated by Clion.

1. Fixes GCC warnings that do not deserve me writing an indepth
explanation on what needed to be changed.
2. The original mask calculation for OPCODE_MOV makes zero sense because
the bit width for operands[0] is always > 31. I don't know what I was
thinking when I wrote this. The mask is now set to cover 32 and 64-bit
immediate values.

This opcode represents a volotile load of a guest register. This is
needed to handle instructions reading register before it has been
written to within the current basic block.
For example, if `MOVK X0` is the first instruction in the basic block,
we have no IR variable representing X0 yet. So we emit
OPCODE_GET_REGISTER before MOVK. OPCODE_GET_REGISTER tells
the backend "load X0 from guest memory"

The definition BAL_SOURCE_SIZE isnt really usefull for Ballistic. Its
mainly use to create a mask for the IR source bitfield. SoI created two
definitions to replace this: BAL_SOURCE_MASK and
BAL_SOURCE_MASK_WITH_FLAG.

The engine is built for 32-bit constants which is wrong since Ballistic
is an ARM64 recompiler. Instructions like MOVZ with LSR #32 or LSR #48
would fail.

This was created to make creating instructions easier to test
Ballistic's translation loop. Documentation will be added in the
future.
