mdbx-windows: remove MDBX_CONFIG_MANUAL_TLS_CALLBACK
build option and add MDBX_MANUAL_MODULE_HANDLER
macro.
Briefly: - Now constructor/destructor of "Thread Local Storage" handled automatically when possible. - Otherwise the MDBX_CONFIG_MANUAL_TLS_CALLBACK macro defined to 1 to indicate that mdbx_module_handle() should be called manually. - Corresponding build option MDBX_CONFIG_MANUAL_TLS_CALLBACK was removed. Related to https://github.com/erthink/libmdbx/issues/155 Change-Id: Ic4e6a34b44f874676f0ab212ff473460e3d80559
