The x64 bridge backport in ebdb555 brought these files over from origin/windows-amd64, a branch predating the tree-wide whitespace cleanups in #383 and #462, so it silently reintroduced trailing whitespace in the license headers of call.asm, cpp2uno.cxx and except.cxx plus a stray blank line at the end of except.cxx. Since the pre-commit workflow runs with --all-files, this fails the check on every pull request against trunk, not just ones touching these files.

* bridges/msvc_win64: pass simple argument values, not the temp's address
uno2cpp.cxx converts each simple by-value argument into an 8-byte alloca
temp and stores the pointer in pCppArgs[nPos]:
uno_copyAndConvertData( pCppArgs[nPos] = alloca( 8 ), ... );
Copying the value into the outgoing slot therefore has to dereference that
pointer. The marshalling switch used &pCppArgs[nPos] instead, which reads
the pCppArgs array slot itself, i.e. the temp's address -- so every HYPER,
LONG, ENUM, SHORT, CHAR, BOOLEAN, BYTE, FLOAT and DOUBLE parameter reached
the callee as a stack address (or its low 16/32 bits) rather than a value.
The same expression is correct in the complex/ref branch, where the pointer
IS the argument; written there as (sal_uInt64)pCppArgs[nPos] to make the
difference between the two branches obvious.
This only affects calls that cross between the uno and cpp environments, so
a pure-C++ session never trips it; it surfaces via pyuno and the invocation
adapters.

* bridges/msvc_win64: return queryInterface's Any in the hidden return buffer
The Win64 call stack is "ret addr, this, [ret *], params", so a method with
a hidden return pointer finds it at pCallStack[2] -- cpp2uno_call() reads
pCppReturn from [2], and the queryInterface shortcut in cpp_mediate() reads
its Type argument from [3] accordingly.
That shortcut nevertheless built the returned Any at pCallStack[1] and
returned [1] in the register slot. [1] is `this`, so it constructed a
24-byte Any over the proxy object and never wrote the caller's own return
buffer. The caller then read and destructed an uninitialised Any, faulting
in uno_any_destruct() on a stale stack value used as a
typelib_TypeDescription*.
The x86 bridge has always used pCallStack[2] here; the Win64 port carried
over the x86 index, where the layout puts the hidden pointer before `this`.
Reproducer: any queryInterface on a raw uno_Interface proxy -- e.g. pyuno's
Adapter::getOutIndexes() inspecting an InvocationAdapterFactory adapter,
which crashed on every use of the Python macro organiser.

* pre-commit: fix whitespace in the msvc_win64 bridge sources
The x64 bridge backport in ebdb555 brought these files over from
origin/windows-amd64, a branch predating the tree-wide whitespace
cleanups in #383 and #462, so it silently reintroduced trailing
whitespace in the license headers of call.asm, cpp2uno.cxx and
except.cxx plus a stray blank line at the end of except.cxx.
Since the pre-commit workflow runs with --all-files, this fails the
check on every pull request against trunk, not just ones touching
these files.
