Bugfix
* Fix #5758. Compilers might generate unexpected instructions when CPU
modifiers were specified as global flags( command line or global headers).
It is fixed with reducing the scope of CPU modifier flags.
* Fix an issue when compiling with MBEDTLS_SHA512_USE_A64_CRYPTO_IF_PRESENT
enabled, which required specifying compiler flags enabling SHA3 Crypto
Extensions, where some compilers would emit EOR3 instructions in other
modules, which would then fail if run on a CPU without the SHA3
extensions. Fixes #5758.
Changes
* When enabling MBEDTLS_SHA256_USE_A64_CRYPTO_* or
MBEDTLS_SHA512_USE_A64_CRYPTO_*, it is no longer necessary to specify
compiler target flags on the command line; the library now sets target
options within the appropriate modules.
