Compiler warnings ("defined but not used") in "nimble/host/mesh/src/proxy_srv.c"

Hi.

When compiling with all warnings ON, I get the following warning messages:

/home/runner/Arduino/libraries/NimBLE-Arduino/src/nimble/nimble/host/mesh/src/proxy_srv.c:637:13: warning: 'proxy_ccc_write' defined but not used [-Wunused-function]
  637 | static void proxy_ccc_write(uint16_t conn_handle)

FQBN: esp32:esp32:esp32
h2zero/NimBLE-Arduino version: 2.3.0

This warning may be a symptom of something worse. Either those functions are certainly not called, either some preprocessor directives are missing.

Hello @afpineda, those are safe to ignore, they only occur because the mesh proxy is not enabled so they are not called.
