CMake's language is rather fragile and unsound. For the most part, it is
a shell script with more parentheses. That is, it simply expands command
arguments into a list of strings and then evaluates it, complete with
shell-style differences between "${FOO}" and ${FOO}.
The if() command is special and internally also expands variables. That
is why things like if(FOO STREQUAL "BAR") work. CMake interprets "FOO"
as a variable if it can find a variable, or a string otherwise. In
addition to getting very confused on typos, it means that
if("${FOO}" STREQUAL "BAR") will double-expand, and it will do strange
things if BAR is a variable.
CMP0054 patches this (which we set by minimum version) so that if() only
expands if the token was unquoted. This fixes
if("${FOO}" STREQUAL "BAR"). However, if(${FOO} STREQUAL "BAR")
continues to double-expand FOO.
We had a mix of all three of FOO, ${FOO}, and "${FOO}". It's not clear
which is the canonical spelling at this point, but CMake own files
(mostly) use FOO, as do most of our lines, so I've standardized on that.
It's a little unsatisfying if we typo a variable, but I suppose ${FOO}
also silently ignores unset variables.

Windows on Arm (WoA) builds are currently using the C implementations
of the various functions within BoringSSL. This patch enables feature
detection for the Neon and hardware crypto optimizations, and updates
the perl script to generate AArch64 .S files for WoA.
Note these files use GNU assembler syntax (specifically tested with
Clang assembler), not armasm.

This change causes the run_tests target, in FIPS builds, to run ACVP
for each supported algorithm. For most of them the output can be compared
against a known result. For some of them the output is too variable and
they are only run to ensure that they don't have local errors.
The ACVP test vectors have been trimmed significantly because they're
often huge. Firstly an included tool drops all but one test from each
group. Some vector sets have been manually trimmed to remove tests that
cause variable output.
