[lldb/ObjectFileMachO] Fetch shared cache images from our own shared cache

[lldb/ObjectFileMachO] Fetch shared cache images from our own shared cache
Summary:
On macOS 11, the libraries that have been integrated in the system
shared cache are not present on the filesystem anymore. LLDB was
using those files to get access to the symbols of those libraries.
LLDB can get the images from the target process memory though.
This has 2 consequences:
- LLDB cannot load the images before the process starts, reporting
an error if someone tries to break on a system symbol.
- Loading the symbols by downloading the data from the inferior
is super slow. It takes tens of seconds at the start of the
debug session to populate the Module list.
To fix this, we can use the library images LLDB has in its own
mapping of the shared cache. Shared cache images are somewhat
special as their LINKEDIT segment is moved to the end of the cache
and thus the images are not contiguous in memory. All of this can
hidden in ObjectFileMachO.
This patch fixes a number of test failures on macOS 11 due to the
first problem described above and adds some specific unittesting
for the new SharedCache Host utilities.
