If dynamic interrupts are enabled, a set of trampoline stubs
are generated which transfer control to a common dynamic
interrupt handler function, which then looks up the proper
handler and parameter and then executes the interrupt.
Based on the prior x86 dynamic interrupt implementation which
was removed from the kernel some time ago, and adapted to
changes in the common interrupt handling code, build system,
and IDT generation tools.
An alternative approach could be to read the currently executing
vector out of the APIC, but this is a much slower operation.

intList has been populated with the number of isrs, aka interrupts,
but nothing has not been using this information so we drop it and
everything used to construct it.

It is desired behaviour that when 'make VERBOSE=1' is invoked, the
underlying scripts will be invoked in 'verbose mode', e.g. they have
the flag --verbose passed to them.
This patch modifies all the underlying scripts in the build system to
inject --verbose into the command line when the environment variable
VERBOSE is set.
The environment variable VERBOSE is a CMake concept. CMake will
generate Makefile's that read this environment variable and try to
behave accordingly. Unfortunately, the generated ninja build systems
behave differently and will have to be invoked like this:
VERBOSE=1 ninja -v
This fixes#4851

This has one use-case: configuring the double-fault #DF
exception handler to do an IA task switch to a special
IA task with a known good stack, such that we can dump
diagnostic information and then panic.
Will be used for stack overflow detection in kernel mode,
as otherwise the CPU will triple-fault and reset.

This is one less host tool we have to compile for every build,
and makes the build tools more portable across host OSes.
The code is also much simpler to maintain.
