SetLastChanceExceptionHandler sets a callback to be called after a
crash has been reported. Returning true from this callback will
not reraise the signal so the execution can continue. This will be
used to implement permissive MTE mode, which will continue execution
after a MTE crash.

SA_EXPOSE_TAGBITS is a Linux >= 5.11 feature that allows si_addr to
contain the upper tag bits. This is a feature that allows signal
handlers to see the full upper address bits on aarch64, which consist of
TBI and MTE nibbles. For MTE, preserving these bits is of significant
importance, as it allows for precise use-after-free and buffer-overflow
diagnosis that's impossible without seeing these bits in the fault
address.
We unconditionally enable this feature on all kernels, as it's ignored
when unsupported (even on older kernels).
Tested on:
1. Linux x86 host, which is a no-op.

handler_sock end of the socketpair is donated to the crashpad server
process which owns it. The client should not keep it open. Otherwise
if the crashpad server process crashes and the client is reading from
client_sock, the client will hang forever because the other end is still
open.
This happens when:
- /proc/sys/kernel/yama/ptrace_scope file is present.
- crashpad is invoked with missing required fields, like --database.
In this case, chrome hangs until timeout.

The thread_local disabled_for_thread_ is removed and combined with this

This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.
