HF one entry point (#7393)

Add one entry point for all HF for centralized exceptions handling, gas calculation and general checks.
Add exception handling for HF
Add FieldLocator object
Switch pointers to references for HF and runtime
Max size for parameters and sfData field is 1 kb now
Fix Allhf unittest, to provide correct locator

-     - "thread"

-     * -mcmodel=large/medium: (GCC only) Code model for large binaries
-     * -Wno-stringop-overflow: (GCC only) Suppresses false positive warnings
-     * -Wno-tsan: (For GCC TSAN combination only) Suppresses atomic_thread_fence warnings
-
-   - SANITIZERS_LINK_FLAGS: Linker flags for sanitizer runtime libraries.
-     Includes:
-     * -fsanitize=<types>: Links sanitizer runtime libraries
-     * -mcmodel=large/medium: (GCC only) Matches compile-time code model
-
-   - SANITIZERS_RELOCATION_FLAGS: (GCC only) Code model flags for linking.
-     Used to handle large instrumented binaries on x86_64:
-     * -mcmodel=large: For AddressSanitizer (prevents relocation errors)
-     * -mcmodel=medium: For ThreadSanitizer (large model is incompatible)
+   The flags are applied to the 'common' interface library which is linked to all targets in the project.

-export SANITIZERS=address,undefinedbehavior

-Do not mix Address and Thread sanitizers - they are incompatible.

-Since you already set the `SANITIZERS` environment variable when running Conan, same values will be read for the next part.

 **Why `detect_container_overflow=0`?**
 
-- Boost intrusive containers (used in `aged_unordered_container`) trigger false positives
+- Boost intrusive containers (used in `AgedUnorderedContainer`) trigger false positives
 - Boost context switching (used in `Workers.cpp`) confuses ASAN's stack tracking
 - Since we usually don't build Boost (because we don't want to instrument Boost and detect issues in Boost code) with ASAN but use Boost containers in ASAN instrumented xrpld code, it generates false positives.
 - Building dependencies with ASAN instrumentation reduces false positives. But we don't want to instrument dependencies like Boost with ASAN because it is slow (to compile as well as run tests) and not necessary.
