Because the log message "Tombstone written to: $NAME" is written
before renaming the proto tombstone, it is possible that a tool that
automatically downloads new proto tombstones by watching for this
log message will fail to download the tombstone. For the tool that
I am developing, this occurs < 0.1% of the time. Fix the issue by
renaming the proto tombstone first.

Extends the recoverable native crash handling support to also allow for
MTE crashes to be recovered from in apps. Backs onto the existing
GWP-ASan recoverable handling.
At least for system/core, I've renamed the (now) generic "recoverable
crash" variables to remove the notion of GWP-ASan.
Permissive MTE should no longer crash an app, and crashes are still
visible in the AppExitInfo API and tombstones.

The code was only meant for native tombstones. It might be a good idea
to make ANRs also readable by shell / adb, but in that case we have to
do more changes to make sure all files in /data/anr are. We can revert
if we implement that

This reverts commit d059478ee1.
Reason for revert: Potential culprit for b/327525776- verifying through ABTD before revert submission. This is part of the standard investigation process, and does not mean your CL will be reverted.

They are still restricted by SELinux, and apps still cannot open them
because they don't have `open` SELinux permission.

A few files were changed without using the generate script. Modify
the original policy file and generate all of the policy files
properly.
Test: Verify the generated files are the same as before.

Two things need changing for debuggerd_test to pass.
1. The seccomp policy needs to allow for PROT_MTE (0x20) in both
mprotect() and mmap(). Stack MTE processes do a mprotect()/mmap() of
the stack when launching a process.
2. The fault address and stack pointer need to be untagged when trying
to figure out the stack overflow cause.

This is a no-op but will be used in upcoming scudo changes that allow to
change the depot size at process startup time, and as such we will no
longer be able to call __scudo_get_stack_depot_size in debuggerd.
