TLS code already implements proper dispatching to either
builtin or PSA implementations based on USE_PSA guards, so we can

PBKDF2-AES-CMAC works if we provide the driver of AES-CMAC or
KEY-TYPE-AES or both. So if PBKDF2-AES-CMAC is requested via PSA,
we don't need to additionally enable builtin AES-CMAC or builtin
KEY-TYPE-AES.

ECP_LIGHT is not usable without any curve, just the same as ECP_C.
We forgot to update this check when introducing the ECP_LIGHT subset.
Note: the message doesn't mention ECP_LIGHT as that's not a public
config knob, hence the message with "ECP_C or a subset" (that's how it's
referred to in user-facing documentation such as
docs/driver-only-builds.md).

Tested manually as follows: in
component_test_psa_crypto_config_accel_ecc_some_key_types, modify
loc_accel_list to remove one of the key types between
helper_libtestdriver1_make_drivers and helper_libtestdriver1_make_main,
and observe that the 2nd build fails with the expected #error.
Note: removing one of the key types before
helper_libtestdriver1_make_drivers causes the build of libtestdriver1 to
fail, which is quite acceptable, just not what we're trying to observe.

I chose to divide along the lines of Weierstrass vs other curve shapes

The previous fix was enabling more than needed in some circumstances,
for example:
- requested: (`PSA_WANT`): all ECC algs, all ECC key types, all curves;
- we have acceleration (`MBEDTLS_PSA_ACCEL`) for: ECDH, all ECC key types, all curves;
- as a consequence, we need built-in: all algs except ECDH, all ECC key types, all curves.
This is what's happening in test_psa_crypto_config_accel_ecdh which,
before this commit, was failing as built-in ECDH was enabled contrary to
the component's (rightful) expectations.

Centralize it in a new file psa/config_adjust_keypair_types.h. I think
this file indeed belongs in include/psa (as opposed to include/mbedtls)
because it only touches PSA_WANT symbols (no MBEDTLS_PSA symbols), and
implements things that are described in psa-conditional-inclusion.md.
The code is not new, just moved from config_psa.h and
config_adjust_legacy_from_psa.h where is was intermingled with handling
of ACCEL/BUILTIN symbols. (git's --color-moved option will hardly help
in checking that assertion, due to the way things were intermixed.)
Note: the parts about BUILTIN in config_psa.h were not moved, just
removed for now. They belong to
include/mbedtls/config_adjust_legacy_from_psa.h and will be
re-added there in a future commit which will completely re-organize the
handling or ACCEL/BUILTIN for ECC.
See comments inside the commit about placement of this file relative to
others.

This slightly changes the previous requirement. Instead of enabling
ALL builtin EC algs when there is at least 1 built in curve, we ask
for at least one built alg if there is at least one builtin curve.
This relaxes the previous check while still keeping the base idea:
there must be a reason for which builtin curves are included into
the build.

Conflicts:
* `include/mbedtls/build_info.h`: a new fragment to auto-enable
`MBEDTLS_CIPHER_PADDING_PKCS7` was added in
c9f4040f7f in `development-restricted`.
In `development`, this section of the file has moved to
`include/mbedtls/config_adjust_legacy_crypto.h`.
* `library/bignum.c`: function name change in `development-restricted` vs
comment change in development. The comment change in `development` is not
really relevant, so just take the line from `development-restricted`.
We don't normally make promises related to code size, but this one is vague
enough (just "to benefit"), and it's what a lot of users of this option
care about.

The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":
```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```
Justification for the omissions:
* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
occurrences are significant names in certificates and such. Changing
the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
updates.

Mbed TLS can be configured by writing a configuration file from scratch,
without copying mbedtls_config.h. As a consequence, all the macro
definitions in mbedtls_config.h must be optional. This was not the case for

tickets. Fix that.

Boolean options that modify the behavior of a module are supposed to be in
the "feature support" section, not in the "configuration options" support:
that section is documented to contain commented-out definitions with a
value, for which the comment contains the default version. In particular,
merely uncommenting a definition in the "configuration options" section is
not supposed to change anything.
Move the offending boolean options to the proper section.
This causes those options to be enabled by `config.py full` unless
explicitly excluded. For all the offending options, this is undesirable, so
make sure those options are indeed excluded.

MBEDTLS_CIPHER_ENCRYPT_ONLY is an internal configuration which is
automatically enabled via the PSA. Typically,
once MBEDTLS_CIPHER_ENCRYPT_ONLY is enabled,
MBEDTLS_PSA_CRYPTO_CONFIG must be enabled. This check is only used
to prevent user explicitly enabling MBEDTLS_CIPHER_ENCRYPT_ONLY.
In addition, we shouldn't enable MBEDTLS_CIPHER_ENCRYPT_ONLY if
either CIPHER_MODE_CBC, CIPHER_MODE_XTS or NIST_KW_C is enabled.
Since three of them always need AES-decrypt.
