[feature] pass strip executable via MesonToolchain

[valgur]

What is your suggestion?

When cross-compiling a Meson project with Conan, the meson setup command complains that

WARNING: Cross file does not specify strip binary, result will not be stripped.

The strip executable value in tools.build:compiler_executables is already supported by GnuToolchain and is almost mandatory for cross-compiling quite a few Autotools projects correctly. Could you please include this info in the generated conan_meson_native.ini and conan_meson_cross.ini as well to fix that warning?

Have you read the CONTRIBUTING guide?
