fix(build): Don't compile metal shaders for android or wasm (#13015) 19d8fb7957
Previously, we were always building the metal shaders on an Apple host,
even if targeting Android or WASM. In addition to being needless bloat,
this started causing issues on CI when the Xcode Metal toolchain was not
present. Only build the metal shaders when needed.
