No need to keep these whitelisted functions decorated with SAL_CALL

The only effect SAL_CALL effectively has on LO-internal code is to change non-
static member functions from __thiscall to __cdecl in MSVC (where all other
functions are __cdecl by default, anyway).  (For 3rd-party code, it could be
argued that SAL_CALL is useful on function declarations in the URE stable
interface other than non-static member functions, too, in case 3rd-party code
uses a compiler switch to change the default calling convention to something
other than __cdecl.  But loplugin:salcall exempts the URE stable interface,
anyway.)

One could argue that SAL_CALL, even if today it effectively only affects non-
static member functions in MSVC, could be extended in the future to affect more
functions on more platforms.  However, the current code would already not
support that.  For example, 3af500580b1c82eabd60335c9ebc458a3f68850c
"loplugin:salcall fix functions" changed FrameControl_createInstance in
UnoControls/source/base/registercontrols.cxx to no longer be SAL_CALL, even
though its address (in ctl_component_getFacrory, in the same file) is passed to
cppuhelper::createSingleFactory as an argument of type
cppu::ComponentInstantiation, which is a pointer to SAL_CALL function.
