Add event log message for failed validation

Tested manually by installing Chrome Dev, then trying to decrypt
data from an invalid process, causing the event to trigger. I
couldn't think of a good way to automate these tests.

The event log message looks like this:

```
Event Xml:
<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
  <System>
    <Provider Name="Chrome Dev" />
    <EventID Qualifiers="32769">257</EventID>
    <Version>0</Version>
    <Level>3</Level>
    <Task>2</Task>
    <Opcode>0</Opcode>
    <Keywords>0x80000000000000</Keywords>
    <TimeCreated SystemTime="2024-04-05T04:18:05.8564626Z" />
    <EventRecordID>7529</EventRecordID>
    <Correlation />
    <Execution ProcessID="0" ThreadID="0" />
    <Channel>Application</Channel>
    <Computer>DESKTOP-7L90PGP</Computer>
    <Security UserID="S-1-5-18" />
  </System>
  <EventData>
    <Data>[0404/211805.856:WARNING:caller_validation.cc(141)] Failed to authenticate caller process: C:\Users\user\Desktop\malware.exe</Data>
  </EventData>
</Event>
```

Because full path is needed in the event log, the code is
restructured a little bit as a result, but all the tests remain
the same.

The generated files are generated using command
`mc chrome\common\win\eventlog_messages.mc` from a
Visual Studio Command Prompt.
