6c09325838 C/C++ Overlay: Preserve entities that have at least one location in an unchanged file 
Previously, an entity would be discarded if it had any location in a changed
file. This caused issues for entities with multiple declaration entries, such
as extern variables declared in one file and defined in another.

For example, given:
  // a.c (changed)       // b.c (unchanged)
  extern int x;          int x;

The variable `x` should be preserved because it has a location in the
unchanged file b.c, even though it also has a location in the changed file a.c.

caf6b950ac Remove trailing periods from @name metadata in query files 
Fixed 73 .ql query files where the @name metadata contained an ending period.
This ensures consistency with the CodeQL query metadata style guidelines.

33c7057066 C++: Remove incorrect tests 
`__has_feature` is not available in GCC versions before GCC 14.

Our frontend was exposing `__has_feature` when emulating earlier versions of
GCC. This will be fixed with the latest major frontend update though.

b293dfe3a6 C++: Fix CWE-119 memcpy tests 
sizeof(pointer) only gives the pointer size, not the buffer
size, so use explicit 10/20 lengths in tests.cpp and update
OverflowBuffer.expected to accept the resulting memcpy diagnostics.
