[PATCH v3 00/12] Enable New CodeQL Queries

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

Adds queries for the following:

1. cpp/conditionallyuninitializedvariable
2. cpp/pointer-overflow-check
3. cpp/overrunning-write
4. cpp/overrunning-write-with-float
5. cpp/very-likely-overrunning-write

These check for vulnerabilities with the following CWEs:

  - https://cwe.mitre.org/data/definitions/120.html
  - https://cwe.mitre.org/data/definitions/457.html
  - https://cwe.mitre.org/data/definitions/676.html
  - https://cwe.mitre.org/data/definitions/758.html
  - https://cwe.mitre.org/data/definitions/787.html
  - https://cwe.mitre.org/data/definitions/805.html

The first part of this patch series contains fixes for CodeQL alerts
across various packages that are produced by the new queries being
enabled.

The second part updates the CodeQL queries.
