This reverts commit d3d5751a39452327690b4e011a23de8327f02e86.
This change addresses CodeQL format-string warnings across multiple
sanitizer libraries by adding explicit casts to ensure that printf-style
format specifiers match the actual argument types.
Key updates:
- Cast pointer arguments to (void*) when used with %p.
- Use appropriate integer types and specifiers (e.g., size_t -> %zu,
ssize_t -> %zd) to avoid mismatches.
- Fix format specifier mismatches across xray, memprof, lsan, hwasan,
dfsan.
These changes are no-ops at runtime but improve type safety, silence
static analysis warnings, and reduce the risk of UB in variadic calls.

Follow on companion to the clang/llvm instrumentation support in D85948
and committed earlier.
This patch adds the compiler-rt runtime support for the memory
profiling.
Note that much of this support was cloned from asan (and then greatly
simplified and renamed). For example the interactions with the
sanitizer_common allocators, error handling, interception, etc.
The bulk of the memory profiling specific code can be found in the
MemInfoBlock, MemInfoBlockCache, and related classes defined and used
in memprof_allocator.cpp.
For now, the memory profile is dumped to text (stderr by default, but
honors the sanitizer_common log_path flag). It is dumped in either a
default verbose format, or an optional terse format.
This patch also adds a set of tests for the core functionality.
