Remove function sanity_check() for contexts

[eric-hughes-tiledb]

The function sanity_check() for contexts has returned a constant TILEDB_OK for a while now; that check was moved into the exception wrappers. At the time, the function was stubbed out to avoid combining the large number of lines that would change with other, more significant ones. This PR completes the removal of this function.

I was confused about the CI error so I went and looked and it appears to be at least one spot where the only use of ctx in the function was passing it to the sanit_check function you removed:

/home/runner/work/TileDB/TileDB/tiledb/sm/c_api/tiledb.cc: In function ‘int32_t tiledb::api::tiledb_uri_to_path(tiledb_ctx_t*, const char*, char*, uint32_t*)’:
/home/runner/work/TileDB/TileDB/tiledb/sm/c_api/tiledb.cc:3258:19: error: unused parameter ‘ctx’ [-Werror=unused-parameter]
 3258 |     tiledb_ctx_t* ctx, const char* uri, char* path_out, uint32_t* path_length) {
      |     ~~~~~~~~~~~~~~^~~

unused parameter

I had a mismatch in capnp version because vcpkg dependencies apparently don't propagate to become dependencies of targets. tiledb.cc was failing in this way so I didn't see the error locally. Fixed that, and saw that it was the only occurrence.
