lib: Use __ASSEMBLER__ instead of __ASSEMBLY__

Convert all non-x86 #ifdefs from __ASSEMBLY__ to __ASSEMBLER__, and remove
all manual __ASSEMBLY__ #defines. __ASSEMBLY_ was inherited blindly from
the Linux kernel, and must be manually defined, e.g. through build rules
or with the aforementioned explicit #defines in assembly code.

__ASSEMBLER__ on the other hand is automatically defined by the compiler
when preprocessing assembly, i.e. doesn't require manually #defines for
the code to function correctly.

Ignore x86, as x86 doesn't actually rely on __ASSEMBLY__ at the moment,
and is undergoing a parallel cleanup.

arm64: timer: Write to ICENABLER to disable timer IRQ

According the Generic Interrupt Controller versions 2, 3 and 4 architecture
specifications, a write of 0 to the GIC{D,R}_ISENABLER{,0} registers is
ignored; this is also how KVM emulates the corresponding register. Write
instead to the ICENABLER register when disabling the timer interrupt.

Note that fortunately for us, the timer test was still working as intended
because KVM does the sensible thing and all interrupts are disabled by
default when creating a VM.
