8c7c1c84cb Add a generic SubjectPublicKeyInfo decoder
Previously all the SubjectPublicKeyInfo decoders were specific to a key
type. We would iterate over all them until a match was found for the correct
key type. Each one would fully decode the key before then testing whether
it was a match or not - throwing it away if not. This was very inefficient.

Instead we introduce a generic SubjectPublicKeyInfo decoder which figures
out what type of key is contained within it, before subsequently passing on
the data to a key type specific SubjectPublicKeyInfo decoder.

Fixes #15646

6a2b8ff392 Decoding PKCS#8: separate decoding of encrypted and unencrypted PKCS#8
This has us switch from the 'structure' "pkcs8" to "PrivateKeyInfo",
which is sensible considering we already have "SubjectPublicKeyInfo".
We also add "EncryptedPrivateKeyInfo", and use it for a special decoder
that detects and decrypts an EncryptedPrivateKeyInfo structured DER
blob into a PrivateKeyInfo structured DER blob and passes that on to
the next decoder implementation.

The result of this change is that PKCS#8 decryption should only happen
once per decoding instead of once for every expected key type.
Furthermore, this new decoder implementation sets the data type to the
OID of the algorithmIdentifier field, thus reducing how many decoder
implementations are tentativaly run further down the call chain.

202cbdd2fc A few cleanups of the provider build.infos
Remove a TODO that is no longer relevant and
drop some more non-fips sources from the fips checksums.

848af5e8fe Drop libimplementations.a
libimplementations.a was a nice idea, but had a few flaws:

1.  The idea to have common code in libimplementations.a and FIPS
    sensitive helper functions in libfips.a / libnonfips.a didn't
    catch on, and we saw full implementation ending up in them instead
    and not appearing in libimplementations.a at all.

2.  Because more or less ALL algorithm implementations were included
    in libimplementations.a (the idea being that the appropriate
    objects from it would be selected automatically by the linker when
    building the shared libraries), it's very hard to find only the
    implementation source that should go into the FIPS module, with
    the result that the FIPS checksum mechanism include source files
    that it shouldn't

To mitigate, we drop libimplementations.a, but retain the idea of
collecting implementations in static libraries.  With that, we not
have:

libfips.a

    Includes all implementations that should become part of the FIPS
    provider.

liblegacy.a

    Includes all implementations that should become part of the legacy
    provider.

libdefault.a

    Includes all implementations that should become part of the
    default and base providers.

With this, libnonfips.a becomes irrelevant and is dropped.
libcommon.a is retained to include common provider code that can be
used uniformly by all providers.

Fixes #15157

f4e46b817d PROV: Add type specific MSBLOB and PVK decoding for the MS->key decoders
To make this cleaner, decoder_ms2key.c is split into decoder_msblob2key.c
and decoder_pvk2key.c.

This required a great deal of refactoring of crypto/pem/pvkfmt.c, to
make cleaner internal functions that our decoder implementations can
use.

8ae40cf57d ENCODER: Refactor provider implementations, and some cleanup
The encoder implementations were implemented by unnecessarily copying
code into numerous topical source files, making them hard to maintain.
This changes merges all those into two source files, one that encodes
into DER and PEM, the other to text.

Diverse small cleanups are included.
