shell-global: Make saving of persistent state asynchronous
This is an expensive operation that is best avoided in the main loop. Given
the call doesn't care much about returning error or status, it can just
be made async within.
Every operation on a given file will be destructive wrt previous
operations on the same file, so we just cancel any pending operation on
it before batching the current one.
keyboardManager: Avoid idempotent calls to meta_backend_set_keymap()
But still try to apply the keymap whenever the input sources changed. This
is a different approach to gnome-shell#240 that still avoid redundant
changes to the current keymap, but actually trigger one when input sources
are added.

appDisplay: use ShellAppCache to access GAppInfo
Calls to Gio.AppInfo.get_all() can perform quite a bit of I/O on the
calling thread. This can potentially stall the compositor if the disk
controller is saturated.
Instead we can call the new ShellAppCache which contains cached information
and performs all update I/O on a thread.
Notifications of changes work very similar to GAppInfoMonitor via the
ShellAppCache::changed() signal.

appDisplay: use ShellAppCache to translate folder names
This was performing quite a bit of I/O on the main thread previously. Now,
all the I/O is deferred to a worker thread and the translated names are
cached for immediate lookup.

ShellAppCache: add cache to help keep I/O off main thread
A number of things can result in doing I/O on the main thread such as
loading GAppInfo or folder translations. The ShellAppCache provides a
layer of abstraction around those things so that we can keep that work
off the main thread by delaying a short while and processing the work
synchronously off-main-thread.
The results can then be marshalled back to the main thread for use by
the rest of the system via the ShellAppCache::changed() signal.

util: cache local GTimeZone
This ensures that we do not create a new GTimeZone with
g_time_zone_new_local() repeatedly. Currently, that will cause GTimeZone
to open(), mmap() and parse /etc/localtime while on the main thread.
We already track timezone changes, so we can cache this value and reuse
it if we:
1) Clear the cache when timezone changes
2) Use the only GDateTime API available to us here, which means we
imply the current time. But this is how environment.js uses the
date and time anyway, so no loss.
We maintain the old form for plugin compatibility.
