We can't have a public header or library file reference our test
environment (except possibly under test-only options, and even so, it would
be with great reluctance). This breaks the build for other people.
Fix#8259.

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.

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
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.

Numeric options should be commented out with their default values in the config
file, and a separate header file should set the default value if necessary.
This was done for most other options in #8161; do it here for
MBEDTLS_SSL_MAX_EARLY_DATA_SIZE.

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.

This is not required (it's ok to define the default in mbedtls_config and

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
some MBEDTLS_SSL_TLS1_3_xxx macros with numerical values related to session
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.
