[Darwin] Fix availability of exp10 for BridgeOS, DriverKit. (#9022)

* [Darwin] Add exp10(f) tests for BridgeOS & Driverkit.

(chery-picked from e83ba1e)

* [Darwin] Fix availability of exp10 for BridgeOS, DriverKit. (llvm#100894)

Same as llvm#98542, but also mark
exp10 available on BridgeOS and DriverKit.

Note that BridgeOS currently is not included by isOSDarwin, but it
probably should.

PR: llvm#100894
