A previous change added a ProcessMemorySanitized class, in this change
plumb support for ProcessMemorySanitized into ProcessSnapshotSanitized.
This involves reading whitelisted regions using the a new field in the
SanitizationInformation struct and returning an initialized
ProcessMemorySanitized object from ProcessSnapshotSanitized::Memory().

In preparation for an upcoming change that will introduce a second
whitelist (for memory ranges), rename variables/functions to explicitly
reference the annotations whitelist.

Use-after-return detection happens to currently be enabled on Linux and
Android but is not exclusive to those platforms. Disable tests
incompatible with ASan UAR detection on all platforms.

These fixes are mostly related to address sanitizer causing stack
variables to not be stored on the call-stack. Attempting to disable
safe-stack has no effect.

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.
