Peter Maydell 268c11984e ui/cocoa.m: Remove unnecessary NSAutoreleasePools
In commit 6e657e64cd in 2013 we added some autorelease pools to
deal with complaints from macOS when we made calls into Cocoa from
threads that didn't have automatically created autorelease pools.
Later on, macOS got stricter about forbidding cross-thread Cocoa
calls, and in commit 5588840ff7 we restructured the code to
avoid them.  This left the autorelease pool creation in several
functions without any purpose; delete it.

We still need the pool in cocoa_refresh() for the clipboard related
code which is called directly there.

* the application is inactive (i.e. no events fire) and we don't want to
* wait for another modifier state change to detect such a change.
*
* NSEventModifierFlagCapsLock requires a special treatment. The other flags

*
* NSEventModifierFlagCapsLock
* ---------------------------
*
* If CapsLock state is changed, "up" and "down" events will be fired in
* sequence, effectively updates CapsLock state on the guest.
*
* The other flags
* ---------------
*
* If a flag is not set, fire "up" events for all keys which correspond to
* the flag. Note that "down" events are not fired here because the flags
* checked here do not tell what exact keys are down.
*
* If one of the keys corresponding to a flag is down, we rely on
* -[NSEvent keyCode] of an event whose -[NSEvent type] is
* NSEventTypeFlagsChanged to know the exact key which is down, which has
* the following two downsides:
* - It does not work when the application is inactive as described above.
* - It malfactions *after* the modifier state is changed while the
* application is inactive. It is because -[NSEvent keyCode] does not tell
* if the key is up or down, and requires to infer the current state from
* the previous state. It is still possible to fix such a malfanction by
* completely leaving your hands from the keyboard, which hopefully makes
* this implementation usable enough.
