Trying to migrate Chromium to the "link all the asm files together" strategy broke the aarch64 Android build because some of the ifdef'd out assembly files were missing the .note.gnu.property section for BTI. If we add support for IBT, that'll be another one. To fix this, introduce <openssl/asm_base.h>, which must be included at the start of every assembly file (before the target ifdefs). This does a couple things: - It emits BTI and noexecstack markers into every assembly file, even those that ifdef themselves out. - It resolves the MSan -> OPENSSL_NO_ASM logic, so we only need to do it once. - It defines the same OPENSSL_X86_64, etc., defines we set elsewhere, so we can ensure they're consistent. This required carving files up a bit. <openssl/base.h> has a lot of things, such that trying to guard everything in it on __ASSEMBLER__ would be tedious. Instead, I moved the target defines to a new <openssl/target.h>. Then <openssl/asm_base.h> is the new header that pulls in all those things.
