pw_build: Restrict -Wno-unused-template to Clang

The -Wno-unused-template warning option is Clang-specific. On GCC
compilers (such as arm-zephyr-eabi-gcc), passing this flag produces
spurious diagnostics when compilation fails or generates warnings:
"note: unrecognized command-line option '-Wno-unused-template' may have
been intended to silence earlier diagnostics".

Restrict -Wno-unused-template to Clang across CMake, GN, and Bazel
strict warning configurations, matching the pattern used for the
deprecated-attributes warning exemption.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
