When libyuv is used in Chrome, there are linker errors or other build
errors on the following platforms:
- Android: undefined symbol: __getauxval
- Fuchsia: undefined symbol: __aarch64_sme_accessible
- macOS: undefined symbol: __arm_tpidr2_save
- Windows: Incorrect size for TransposeWxH_SME prologue: 52 bytes of
instructions in range, but .seh directives corresponding to 40 bytes
Restrict libyuv_use_sme to is_linux (which excludes Android and
ChromeOS) to work around these errors.

Extend both the CMake and BUILD.gn configurations to support building a
library with the Arm Scalable Matrix Extension (SME). Add an initial
(empty) rotate_sme.cc source file to populate the library for now.
