[ios] Remove support for building with Xcode clang

Building with Xcode clang (by setting `use_xcode_clang = true`)
is not maintained and only used to build with bitcode enabled.
As ToT clang supports building with -fembed-bitcode (or the
debug variable -fembed-bitcode-marker), there is no point in
keeping the support for building with Xcode clang.

The variable `use_xcode_clang` is still referenced from some
projects build on top of //build and included in Chromium
(such as Angle), so keep a definition of the variable until
those projects have been converted.

Simplify the BUILD.gn variables by applying the following two
transformations after removing the variable from the conditions:
-   `is_ios || is_mac` => `is_apple`
-   `if (a) { if (b) { ... } }` => `if (a && b) { ... }`
