........S. [ZBXNEXT-6042] optimized trigger, calculated item processing by resolving user macros during configuration cache synchronization

* commit 'ae4645be5080ef59cfd0267bc960d99197f77ed3':
  .D........ [ZBXNEXT-6042] updated changelog entry
  ........S. [ZBXNEXT-6042] fixed use of uninitialised variable
  ........S. [ZBXNEXT-6042] removed unused function
  .......PS. [ZBXNEXT-6042] removed redundant initialization
  .......... [ZBXNEXT-6042] added dc_expand_user_macros_in_calcitem() function test suite
  .......... [ZBXNEXT-6042] renamed test suite to match the renamed function
  .......... [ZBXNEXT-6042] moved user macro mocks to separae configcache mocking library
  .......... [ZBXNEXT-6042] merged global and host macro mock code and moved to separate file
  .......... [ZBXNEXT-6042] add first test cases for dc_expand_user_macros_in_func_params() function
  ........S. [ZBXNEXT-6042] added user macro resolving in calculated item formulas during configuration cache sync
  ........S. [ZBXNEXT-6042] fixed internal/external (dc_/zbx_dc_) configuration cache function naming and expression macro expanding without chache locking when polling calculated items
  ........S. [ZBXNEXT-6042] fixed user macro resolving in simple macro function parameters
  .D........ [ZBXNEXT-6042] added changelog entry
  ........S. [ZBXNEXT-6042] removed macro resolving in user parameters during trigger processing because function parameter user macros are already resolved during conifguration cache sync
  ........S. [ZBXNEXT-6042] added function parameter user macro resolving during configuration cache sync
