RFR: 8289275: Remove incorrect __declspec(dllimport) attributes from pointers in jdk.crypto.cryptoki [v2]

[Julian Waters]

> Several instances of function pointers in jdk.crypto.cryptoki are marked with the dllimport attribute, which should only be applied to symbol declarations, of which a typedef'd function pointer is not. This would only be useful if a function pointer defined in the linked dll is desired to be imported, not if the pointer itself is created locally and used to store a function address. In addition to being incorrect, at least on the versions of Visual C++ the JDK supports today, it is also redundant; Typically they are used to avoid an indirect stub that jumps to the proper entry in the import address table, but usage of these typedefs involves loading the address of a function and directly (Usually through GetProcAddress, even in other cases it would simply be set to the address of a function anyway) assigning it to the pointer before immediately dispatching when called, which bypasses this procedure entirely and makes the attribute pointless.

Julian Waters has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains two additional commits since the last revision:

 - Merge branch 'master' into typedefs
 - Remove __declspec(dllimport) from pointers
