11c81df707 Fix aarch64 assembly for bignum multiplication
Add memory constraints to the aarch64 inline assembly in MULADDC_STOP.
This fixes an issue where Clang 12 and 13 were generating
non-functional code on aarch64 platforms. See #4962, #4943
for further details.

d337fbc4cb x86_64 MULADDC assembly: add missing constraints about memory
MULADDC_CORE reads from (%%rsi) and writes to (%%rdi). This fragment is
repeated up to 16 times, and %%rsi and %%rdi are s and d on entry
respectively. Hence the complete asm statement reads 16 64-bit words
from memory starting at s, and writes 16 64-bit words starting at d.

Without any declaration of modified memory, Clang 12 and Clang 13 generated
non-working code for mbedtls_mpi_mod_exp. The constraints make the unit
tests pass with Clang 12.

c662b36af2 Replace all inclusions of config.h
Also remove preprocessor logic for MBEDTLS_CONFIG_FILE, since
build_info.h alreadyy handles it.

1107ee4e44 Add prefix to BYTES_TO_T_UINT_*
These macros were moved into a header and now check-names.sh is failing.
Add an MBEDTL_ prefix to the macro names to make it pass.

4c5819c318 Move bn_mul.h to library/
Move `include/mbedtls/bn_mul.h` to `library/bn_mul.h`.

Update includes and references to `bn_mul.h` to new location.

Also remove internal headers from `cpp_dummy_build.cpp` as it should only
test public headers in the library.
