Reviewed by Michael Saboff.

Make it possible to build with both USE_SYSTEM_CONTENT_PATH and USE_STAGING_INSTALL_PATH
enabled. With USE_STAGING_INSTALL_PATH, all the frameworks and dylibs will be relocated
to a common "StagedFrameworks" directory, but USE_SYSTEM_CONTENT_PATH directs the build
to locate this directory at a different location, i.e. in a system content path. The
presence of USE_STAGING_INSTALL_PATH also disables all targets' current behavior of
creating symlinks into the system content path -- in this configuration, the frameworks
only need to be referenceable from their location in the StagedFrameworks directory.

Throughout this patch, there are multiple common changes to the same build settings:

INSTALL_PATH_PREFIX:
    This variable adds the system content path as a prefix to products' install paths.
    Leave it empty when USE_STAGING_INSTALL_PATH is set, as the effective prefix will
    be baked into WK_OVERRIDE_FRAMEWORKS_DIR via WK_INSTALL_PATH_PREFIX instead.
OUTPUT_ALTERNATE_ROOT_PATH:
    Define this as empty under USE_STAGING_INSTALL_PATH, since we don't need to create
    the symlinks pointing into the system content path.
WK_INSTALL_PATH_PREFIX:
    This variable is used to define a prefix for the override install path when using
    staged frameworks. Use a different prefix under USE_SYSTEM_CONTENT_PATH. Also
    remove a now-unneeded comparison against WK_MACOS_1015. WebKit doesn't support
    building for versions of macOS prior to 10.15, so this *always* would evaluate to
    'MACOS_SINCE_1015'.

No new tests; no behavior should be changed. (Except for output of this particular
build configuration.)

    Modify the definition of INSTALL_PATH so that the "override-ness" of
    WK_USE_OVERRIDE_FRAMEWORKS_DIR takes precedence over USE_SYSTEM_CONTENT_PATH. With
    these two set, WebInspectorUI.framework should end up in the override path (e.g. the
    StagedFrameworks directory), rather than the standard system content path location.
    Also update OUTPUT_ALTERNATE_ROOT_PATH.

    Somewhat unrelated tweak -- remove WK_OVERRIDE_FRAMEWORKS_DIR from this file since
    it is redundant with the definition of this setting in BaseTarget.xcconfig.
* Source/WebKitLegacy/mac/Configurations/Base.xcconfig:
    Update INSTALL_PATH_PREFIX.
* Source/WebKitLegacy/mac/Configurations/WebKitLegacy.xcconfig:
