I chose to divide along the lines of Weierstrass vs other curve shapes
(currently just Montgomery), mainly because it's the first thing that
came to mind.
It happened to reveal an issue in the logic for when (deterministic)
ECDSA and ECJPAKE are built-in, which this commit is also fixing.

This commit adds dependency check when PK_CAN_ECDSA_SIGN or
PK_CAN_ECDSA_VERIFY is enabled but no corresponding ASN1_WRITE_C
or ASN1_PARSE_C is enabled under PSA.

More key management operations only require ECP_LIGHT, except:
- generate (scalar multiplication)
- export (exporting public from private also needs scalar
multiplication).

The usual order is:
- MBEDTLS_PSA_BUILTIN_xxx macro
- MBEDTLS_xxx legacy macros
But curves had it the other way round for some reason.

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
c9f4040f7f3356293e90c58d11f6567def641e08 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.

Only document it with the PSA configuration, not for
MBEDTLS_ECP_DP_SECP256R1_ENABLED, since p256m can't be used with the classic
API.

Now that p256-m is officially a production feature and not just an example,
give it a more suitable name.
