Remove C symbols defined in a Rust FFI crate or file that are either unused or only used in C/C++ unit tests.

If the path doesn't start with

src/

, assume it to be in the

src/redisearch_rs/c_entrypoint

directory. E.g.

numeric_range_tree_ffi

becomes

src/redisearch_rs/numeric_range_tree_ffi

. If the path points to a directory, review the documentation of all Rust files in that directory.

Use analyze-rust-ffi-crate-surface to enumerate and analyze the usage of all the FFI symbols exposed by the Rust crate or file (e.g.
```
extern "C" fn
```
annotated with
```
#[unsafe(no_mangle)]
```
or type definitions).
For each unused symbol:
- Delete its Rust definition.
- Run C/C++ unit tests to ensure the symbol was indeed unused (via
```
./build.sh RUN_UNIT_TESTS
```
  )
For each symbol that is only used in C/C++ unit tests, elaborate a plan to either:
- Refactor the C/C++ unit tests not to use it.
- Remove the C/C++ unit tests (or assertions) that rely on it, since they are prying into the implementation details of the Rust crate.
- Keep the symbol, but mark it as "test only" in the Rust documentation.
