Support for ThinLTO to be enabled implicitly with FDO
Allows for ThinLTO to be enabled once the --features=fdo_implicit_thinlto feature is enabled in the crosstool. Also allows for --features=-thin_lto to override and prevent ThinLTO from being enabled.
This is essentially the same as https://github.com/bazelbuild/bazel/commit/8e3afccd8bea45105752ddeb33bde111c556fb8b but for instrumentation FDO
instead of AFDO.
RELNOTES: None.
