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.

riscv: sbi: Add SUSP tests

Introduce tests for SBI system suspend. The basic test makes
sure it works and other tests make sure it fails as expected
with invalid entry criteria.

To test on QEMU or hardware the firmware needs to support system
suspend. For QEMU, OpenSBI can be told to enable its system
suspend test mode by creating a new DTB which has

opensbi-config {
compatible = "opensbi,config";
system-suspend-test;
};

added to the 'chosen' node. Then, run with '-dtb susp.dtb'.
