vmbase: Define Bionic TLS from Rust Move the definition of __bionic_tls to Rust and generalize accessing it through the TPIDR_EL0 in vmbase::bionic, reducing the amount of ASM we have and giving typed accesses to the TLS from Rust. Use the linker script to now define __stack_chk_guard at an offset from __bionic_tls, which can't be done from Rust. Note that TPIDR_EL0 can't be configured from rust_entry because the compiler will dereference it during function entry to access __stack_chk_guard and Rust doesn't support LLVM's __attribute__((no_stack_protector)).
