If an application bug means that a buffer smaller than is necessary is
passed to various functions then OpenSSL does not spot that the buffer
is too small and fills it anyway. This PR prevents that.
Since it requires an application bug to hit this problem, no CVE is
allocated.
Thanks to David Benjamin for reporting this issue.

OTC recently voted that EVP_PKEY types will be immutable in 3.0. This
means that EVP_PKEY_set_alias_type can no longer work and should be
removed entirely (applications will need to be rewritten not to use it).
It was primarily used for SM2 which no longer needs this call.
Applications should generate SM2 keys directly (without going via an EC
key first), or otherwise when loading keys they should automatically be
detected as SM2 keys.

(2) EVP_PKEY_fromdata() has an additional selection parameter.
(3) EVP_PKEY_fromdata_settable() replaces EVP_PKEY_key_fromdata_settable() and EVP_PKEY_param_fromdata_settable().
EVP_PKEY_fromdata_settable() also uses a selection parameter.

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.

We take the opportunity to constify these functions. They have to

When the internal key is changed, we must count it as muted, so that
next time the affected key is considered for an operation, it gets
re-exported to the signing provider. In other words, this will clear
the EVP_PKEY export cache when the next export attempt occurs.
This also updates evp_keymgmt_util_export_to_provider() to actually
look at the dirty count for provider native origin keys, and act
appropriately.
