This will be used in a later CL to shuttle shadow stack information
from capture to minidumps. For now these fields are zeroed and have
no effect on any platform.
The x64 snapshot context we use no longer directly maps to the early
CONTEXT structure used by Windows (the prelude still matches). This
may cause confusion if people use the size of a snapshot context when
they meant to use sizeof(CONTEXT).

This reverts commit 7f71c57a29cd9cfa719eb7730d8984aaef4adc05.
Reason for revert: Fuchsia has been transitioned to spsr.

> [fuchsia] re-introduce pstate temporarily
>
> https://fuchsia.googlesource.com/garnet/+/master/bin/zxdb/client/minidump_remote_api.cc#127
> still depends on pstate and we cannot run CQ for hard transitions in Fuchsia yet

A ProcessSnapshotSanitized enables filtering possibly sensitive
information from a snapshot.
WebView has different privacy constraints than Chrome and needs to
avoid collecting data in annotations or from stack memory that may
contain PII. This CL enables:
1. Filtering annotations by name using a whitelist.
2. Filtering for crashes which reference a particular module.
3. Redacting non-essential information from stack memory.
This CL does not provide a client interface to enable sanitization.

As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.
test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.
Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

When no SSE (fxsave) context is available but x87 (fsave) context is, use the
x87 context.
This also embeds the x87 FPU opcode from the fxsave fop field in bits 16-26 of
the fsave error_selector field, true to the layout of the fsave structure. See
Intel SDM volume 1 (253665-061) 8.1.10 and figure 8-9.

and its test.
Minidump context structures now interoperate more easily with snapshot
CPUContext structures, while maintaining identical layout to before.
This is facilitated by reusing the Fxsave types for the substructures
which were completely identical, and by using compatible logic to
initialize the minidump and snapshot structures for testing.
