Currently TaskMemory re-implements a number of Read* routines that are
implemented in a platform-independent way in ProcessMemory with access
to a single platform-specific ReadUpTo method. Implement the ReadUpTo
method for TaskMemory and subclass it from ProcessMemory to inherit the
remaining methods.
The ProcessMemoryTests didn't work on macOS because MultiprocessExec
can not access the child process' task port without root privileges or
the task_for_pid entitlement. Create an adaptor class for those tests to
use MachMultiprocess so that the child process sends its task port to
the parent.

Currently, ProcessMemory is only implemented for Linux and Fuchsia.
Implement the interface for Windows as well and re-factor tests to
support it, mostly this consists of using a new ScopedGuardedPage class
instead of ScopedMmap in the ProcessMemory tests.

Building Crashpad with GCC flagged a few potential issues. The issues
don't seem particularly severe, but they are easy enough to fix.
Note that even with these changes, Crashpad will not cleanly build with
GCC (additional patches would be needed to third_party/mini_chromium).

Avoids using pointers shared between parent/child. Explicitly builds the
test strings in the child process, and then passes both the address and
the expected value of the string to the parent process for expectation
checking. This is necessary to have the test work on Fuchsia.
Also renames ...Forked to ...Child.

Avoids fork()ing as per previous tests in this file, necessary for
Fuchsia.
Unfortunately, I believe that mmap()/munmap() aren't actually working
correctly on Fuchsia as tested by the EXPECT_FALSE reads, and so these
tests incorrectly fail. Bug with repro filed upstream at ZX-1631.

Instead of using pointers shared between the parent/child due to fork,
explicitly builds and passes them between processes. This is
unfortunately a bit more verbose, but seems like it tests functionality
a little better, and is required to have the test work on Fuchsia.
Also renames the ...Forked to ...Child to be correct after the change
from Multiprocess to MultiprocessExec.

Instead of allocating test memory in the parent and then forking and
comparing against it, the child does the allocation and passes back the
region's size and address. Additionally, switch the memcmp()s to be
value-based comparisons instead because the region isn't available in
the parent.
Also renames ProcessMemory.ReadForked to .ReadChild to be correct after
the change from Multiprocess to MultiprocessExec.
This is necessary to have the tests work on Fuchsia.
