VS 2017 was released in March 2017, five years ago now. This means VS
2015 is now past our support window.
This will make the unmarked and "vs2017" configs in CI/CQ do the same
thing. I'll follow up with a separate CL in infra/config to switch the
test VS 2019 instead.
Update-Note: BoringSSL may no longer build with VS 2015. Consumers
should upgrade to the latest Visual Studio release. VS 2017 or later is
required.

The stack consumption of the HRSS functions is causing issues in
stack-constrained environments. Therefore allocate many variables on the
heap. This means that several HRSS_ functions now allocate, and thus can
fail, where they couldn't before. Callers that ignore the return value
and don't have crash-on-failure mallocs will still be safe, although
things will fail to decrypt later on.
Somehow, this actually makes key generation _faster_ on my machine. (I
don't know. Better alignment? Fewer L1 collisions?) The other operations
are slightly slower, as expected.
Before:
Did 17390 HRSS generate operations in 3054088us (5694.0 ops/sec)
Did 225000 HRSS encap operations in 3000512us (74987.2 ops/sec)
Did 87000 HRSS decap operations in 3014525us (28860.3 ops/sec)
After:
Did 21300 HRSS generate operations in 3026637us (7037.5 ops/sec)
Did 221000 HRSS encap operations in 3008911us (73448.5 ops/sec)
Did 84000 HRSS decap operations in 3007622us (27929.0 ops/sec)

It's strange to have Serialize/Deserialize methods not inverses of each
other. Split the operation up and move the common parts out of the
subclass.
