dpwa: Serialize WebAppInstallManager error log.
WebAppInstallManager error log may contain critical errors.
If the user has kRecordWebAppDebugInfo flag enabled, critical
errors must survive chrome binary relaunches.
Example path to output file:
/user-data-dir/<ProfileDir>/Web Applications/Logs/WebAppInstallManager.log
This UI exposition is useful on ChromeOS devices where bug reporters
don't have access to the underlying filesystem.
