b350a41a10 Gather more coverage data 
Switch to ForkWithFlags for InitProcess (it will not reset coverage).
Explicitly dump coverage after initial namespace setup.
Return instead of exiting from libunwind sandbox.

eaa175c8d2 Sandbox2: Remove file sealing for in-memory files. 
The `CreateMemFd` function sets the `MFD_ALLOW_SEALING` flag which enables seals to be set and creating an empty file seal.

dbaf95c724 Move utility code into sandboxed_api/util 
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.

d0c8224e61 Add support for ARM32 (hard float target) 
This change enables support for 32-bit ARM, as used by embedded controllers and older phones.
Note: This does not support 32-bit sandboxees on AArch64. Both sandboxee and host code must have the same bitness.

c3ac45be3e Reimplement raw logging to avoid Abseil internals

21f7373e76 Initial changes to support AArch64 
This is a work in progress:
- Syscall tables need work
- Only tested on real hardware using one of our test hosts

As a drive-by, this change also enables the open source version to function on
POWER.

Another side-effect of this change is that the default policies no longer
check for different host architectures at runtime. On x86_64, we do not need
to check for PPC or AArch64 specifice and vice versa.

6a1e4b881c Introduce config header to centralize CPU architecture checks 
This allows us to remove some uses of macros.

Related changes:
- Make it clear that we support hosting sandboxed binaries from 64-bit
  processes only. CPU architectures are x86-64 and POWER64 (little endian).
- Introduced CPU architecture macros, abstracting away compiler specifics
