The cmd/dist cgo_test enumerates a large number of platforms in
various special cases. Some combinations are suspiciously absent. This
CL completes the combinations.

I've confirmed using trybots that the newly-enabled tests pass on
android/* (this is not surprising because the gohostos is never
"android" anyway), windows/arm64, linux/ppc64 (no cgo), linux/loong64
(except for one test, filed #56623), linux/mips*, netbsd/arm (except
for one test, filed #56629), and netbsd/arm64. The windows/arm builder
is out to lunch, so I'm assuming that works. Since netbsd/arm and
arm64 mostly passed these tests, I've also enabled them on netbsd/386
and netbsd/amd64, where they seem to work fine as well.

Preparation for #37486.

Refer to CL 413428 and 412474, for loong64, like mips, s390x and riscv, there
is no single instruction that saves the LR and decrements the SP, so we also
need to insert an instruction to save the LR after decrementing the SP.

Fixes golang#56623.
Updates golang#53374.
