Subject: [PATCH v1 12/12] .github/codeql/edk2.qls: Enable CWE 120, 787, and 805 queries

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

As recommended by CodeQL this change replaces
cpp/potential-buffer-overflow with cpp/overrunning-write-with-float
and cpp/overrunning-write.

Enables:

1. cpp/overrunning-write
- @name Likely overrunning write
- @description Buffer write operations that do not control the length
data written may overflow
- @kind problem
- @problem.severity error
- @security-severity 9.3
- @precision high
- @id cpp/very-likely-overrunning-write
- @tags reliability
- security
- external/cwe/cwe-120
- external/cwe/cwe-787
- external/cwe/cwe-805
2. cpp/overrunning-write-with-float
- @name Potentially overrunning write with float to string conversion
- @description Buffer write operations that do not control the length
of data written may overflow when floating point inputs
take extreme values.
- @kind problem
- @problem.severity error
- @security-severity 9.3
- @precision medium
- @id cpp/overrunning-write-with-float
- @tags reliability
- security
- external/cwe/cwe-120
- external/cwe/cwe-787
- external/cwe/cwe-805
3. cpp/very-likely-overrunning-write
- @name Likely overrunning write
- @description Buffer write operations that do not control the length
of data written may overflow
- @kind problem
- @problem.severity error
- @security-severity 9.3
- @precision high
- @id cpp/very-likely-overrunning-write
- @tags reliability
- security
- external/cwe/cwe-120
- external/cwe/cwe-787
- external/cwe/cwe-805
