[-Wunsafe-buffer-usage] Fix bug in unsafe casts to incomplete types (#116433)
Fixed the crash coming from attempting to get size of incomplete types.
Casting `span.data()` to a pointer-to-incomplete-type should be
immediately considered unsafe.
Solving issue #116286.

[-Wunsafe-buffer-usage] Emit a warning if pointer returned by vector::data and array::data is cast to larger type (#111910)
Emit a warning when the raw pointer retrieved from std::vector and
std::array instances are cast to a larger type. Such a cast followed by
a field dereference to the resulting pointer could cause an OOB access.
This is similar to the existing span::data warning.

[-Wunsafe-buffer-usage] Add a new warning for uses of std::span two-parameter constructors (#77148)
Constructing `std::span` objects with the two parameter constructors
could introduce mismatched bounds information, which defeats the
purpose of using `std::span`. Therefore, we warn every use of such
constructors.

[-Wunsafe-buffer-usage] Fix the crash introduced by the unsafe invocation of span::data warning (#78815)
The patch fixes the crash introduced by the DataInvocation warning
gadget designed to warn against unsafe invocations of span::data method.
It also now considers the invocation of span::data method inside
parenthesis.

[-Wunsafe-buffer-usage] Warning for unsafe invocation of span::data (#75650)
…-Wunsafe-buffer-usage,
there maybe accidental re-introduction of new OutOfBound accesses into
the code bases. One such case is invoking span::data() method on a span
variable to retrieve a pointer, which is then cast to a larger type and
dereferenced. Such dereferences can introduce OutOfBound accesses.
To address this, a new WarningGadget is being introduced to warn against
such invocations.
