Clients now poll the proxy for the latest global config for a specific
version. The proxy now periodically requests the latest global
configuration data and stores it in memory, enabling it to respond
immediately to clients with the appropriate version.
Clients should avoid reading system keys unless authorized. Under global
config, each client reads from the system keyspace to check for new
global config keys. This commit moves these reads to a server role (the
GRV proxies) and sends the results back to GlobalConfig for an in-memory
update.

* Add extra validation to special key space reads in simulation
* Fix bugs turned up by validating subrange reads
* Change to validateSpecialSubrangeRead
It is in general not safe to expect that a read from the special key
space returns the same results if performed again, since the
transaction may be being modified concurrently.

* Don't build fdb c shim with ubsan
This avoids duplicate symbols when linking. It doesn't really make sense
to assemble files with -fsanitize=undefined anyway, since it won't
insert instrumentation.
* Consolidate boost_asan with boost_target
* Fix ASAN build

Backport changes made to TLogServer in #4616 back to old TLog implementations.
Old implementations were using SpecialCounter, which is string. The new type
is int64_t. Without the change, we can have many events like:
<Event Severity="30" Time="1658165532.958152" DateTime="2022-07-18T17:32:12Z" Type="ScopeEventFieldTypeMismatch" ID="0000000000000000" EventType="TraceEvent.TLogMetrics" FieldName="QueueDiskBytesUsed" OldType="Int64" NewType="String" ThreadID="2451559325190099131" Machine="10.242.248.26:4703" LogGroup="xxxx" Roles="TL" />
