With D92696, the Scudo Standalone GWP-ASan flag parsing was changed to
the new GWP-ASan optional one. We do not necessarily want this, as this
duplicates flag parsing code in Scudo Standalone when using the
GWP-ASan integration.
This CL reverts the changes within Scudo Standalone, and increases
`MaxFlags` to 20 as an addionnal option got us to the current max.

Turns out that gtest in LLVM is only 1.8.0 (the newest version 1.10.0)
supports the GTEST_SKIP() macro, and apparently I didn't build w/o
GWP-ASan.
Should fix the GN bot, as well as any bots that may spuriously break on
platforms where the code wasn't correctly ifdef'd out as well.
Summary:
Adds GWP-ASan to Scudo standalone. Default parameters are pulled across from the
GWP-ASan build. No backtrace support as of yet.

Summary:
This CL makes unit tests compatible with Fuchsia's zxtest. This
required a few changes here and there, but also unearthed some
incompatibilities that had to be addressed.
A header is introduced to allow to account for the zxtest/gtest
differences, some `#if SCUDO_FUCHSIA` are used to disable incompatible
code (the 32-bit primary, or the exclusive TSD).
It also brought to my attention that I was using
`__scudo_default_options` in different tests, which ended up in a
single binary, and I am not sure how that ever worked. So move
this to the main cpp.
Additionally fully disable the secondary freelist on Fuchsia as we do
not track VMOs for secondary allocations, so no release possible.
With some modifications to Scudo's BUILD.gn in Fuchsia:
```
[==========] 79 tests from 23 test cases ran (10280 ms total).
[ PASSED ] 79 tests
```
