Fix Windows ZTS shared-build LNK2001 on _tsrm_ls_cache (#1674)

Drop /DZEND_ENABLE_STATIC_TSRMLS_CACHE=1 from the sqlsrv and pdo_sqlsrv
EXTENSION() calls in config.w32.

On thread-safe (ZTS) shared builds this define made init.cpp / pdo_init.cpp
define _tsrm_ls_cache with C linkage (php_sqlsrv.h / php_pdo_sqlsrv.h are
included inside an extern "C" block), while the shared core_*.cpp translation
units reference it with C++ linkage (core_sqlsrv.h includes php.h outside
extern "C"). The linkage mismatch produced:

  core_stmt.obj : error LNK2001: unresolved external symbol
  "void * _tsrm_ls_cache" (?_tsrm_ls_cache@@3PEAXEA)
  fatal error LNK1120: 1 unresolved externals

Removing the define makes the Windows shared build resolve the TSRM cache
through the engine (tsrm_get_ls_cache()), matching the Linux/macOS config.m4
builds and the Windows static build. NTS builds are unaffected.
