Enhance documentation for `BN_mask_bits()`

Fixes #5537

Added a note that the error check for `BN_mask_bits()` depends
on the internal representation that depends on the platform's word size.
Included a reference to the `BN_num_bits()` function for precise bit checking.

Replace and deprecate the functions `TS_VERIFY_CTX_set_data`,

The previous functions had poorly documented memory handling, potentially
leading to memory leaks. The new functions improve memory management and provide
clearer usage.

Also, update existing code to use the new function calls instead of the deprecated
ones.

read lock store on ossl_method_store_do_all

Theres a data race between ossl_method_store_insert and
ossl_method_store_do_all, as the latter doesn't take the property lock
before iterating.

However, we can't lock in do_all, as the call stack in several cases
later attempts to take the write lock.

The choices to fix it are I think:
1) add an argument to indicate to ossl_method_store_do_all weather to
take the read or write lock when doing iterations, and add an
is_locked api to the ossl_property_[read|write] lock family so that
subsequent callers can determine if they need to take a lock or not

2) Clone the algs sparse array in ossl_method_store_do_all and use the
clone to iterate with no lock held, ensuring that updates to the
parent copy of the sparse array are left untoucheTheres a data race
between ossl_method_store_insert and ossl_method_store_do_all, as the
latter doesn't take the property lock before iterating.

I think method (2), while being a bit more expensive, is probably the
far less invasive way to go here

Avoid chicken and egg problem with reg setting

Because openssl with -DOSSL_WINCTX no longer falls back to build time
defines, we have a chicken and egg problem. CI needs to query openssl
for its version string so registry keys can be set properly, but openssl
version refuses to run because no configuration file can be found

So we work around it by, for the purposes of setting the registry keys,
we set OPENSSL_CONF to a know config file, so that openssl version runs
properly.

Once the version is extracted, we can set the registry keys, and openssl
will function properly without OPENSSL_CONF set
