If someone calls an EVP_PKEY_get0*() function then we create a legacy
key and cache it in the EVP_PKEY - but it doesn't become an "origin" and
it doesn't ever get updated. This will be documented as a restriction of
the EVP_PKEY_get0*() function with provided keys.

The idea is to make it as transparent as possible to call things like
EVP_PKEY_CTX_ctrl() with a provider backed EVP_PKEY_CTX, or things
like EVP_PKEY_get_bn_param() with a legacy EVP_PKEY.
All these sorts of calls demand that we translate between ctrl
commands and OSSL_PARAM keys, and treat the arguments appropriately.
This implementation has it being as data driven as possible, thereby
centralizing everything into one table of translation data, which
supports both directions.

The low level DH API has two functions for checking parameters:
DH_check_ex() and DH_check_params_ex(). The former does a "full" check,
while the latter does a "quick" check. Most importantly it skips the
check for a safe prime. We're ok without using safe primes here because
we're doing ephemeral DH.
Now that libssl is fully using the EVP API, we need a way to specify that
we want a quick check instead of a full check. Therefore we introduce
EVP_PKEY_param_check_quick() and use it.

This fixes a race condition where the index to the cache location was found
under a read lock and a later write lock set the cache entry. The issue being
that two threads could get the same location index and then fight each other
over writing the cache entry. The most likely outcome is a memory leak,
however it would be possible to set up an invalid cache entry.
The operation cache was a fixed sized array, once full an assertion failed.
The other fix here is to convert this to a stack. The code is simplified and
it avoids a cache overflow condition.

Added EVP_KEM_* functions.
Added OSSL_FUNC_kem_* dispatch functions
Added EVP_PKEY_CTX_set_kem_op() so that different types of KEM can be added in the future. This value must currently be set to
"RSASVE" after EVP_PKEY_encapsulate_init() & EVP_PKEY_decapsulate_init() as there is no default value.

The default and legacy providers currently return 1 for status and self test checks.
Added test to show the 3 different stages the self test can be run (for installation, loading and on demand).
For the fips provider:
- If the on demand self test fails, then any subsequent fetches should also fail. To implement this the
cached algorithms are flushed on failure.
- getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core
libctx (as it is set by the application) not the actual fips library context. Also the callback can be set at
any time not just during the OSSL_provider_init() so it is calculated each time before doing any self test.

EVP_PKEYs with provider side internal keys got the key type
EVP_PKEY_NONE. This turned out to be too disruptive, so we try
instead to find a matching EVP_PKEY_ASN1_METHOD and use whatever
EVP_PKEY type it uses.
To make internal coding easier, we introduce a few internal macros to
distinguish what can be expected from a EVP_PKEY:
- evp_pkey_is_blank(), to detect an unassigned EVP_PKEY.
- evp_pkey_is_typed(), to detect that an EVP_PKEY has been assigned a
type, which may be an old style type number or a EVP_KEYMGMT method.
- evp_pkey_is_assigned(), to detect that an EVP_PKEY has been assigned
an key value.
- evp_pkey_is_legacy(), to detect that the internal EVP_PKEY key is a
legacy one, i.e. will be handled via an EVP_PKEY_ASN1_METHOD and an
EVP_PKEY_METHOD.
- evp_pkey_is_provided(), to detect that the internal EVP_PKEY key is
a provider side one, i.e. will be handdled via an EVP_KEYMGMT and
other provider methods.
This also introduces EVP_PKEY_KEYMGMT, to indicate that this EVP_PKEY
contains a provider side key for which there are no known
EVP_PKEY_ASN1_METHODs or EVP_PKEY_METHODs, i.e. these can only be
handled via EVP_KEYMGMT and other provider methods.
