Chip Davis fb5ee4cb5c MSL: Adjust BuiltInWorkgroupId for vkCmdDispatchBase().
This command allows the caller to set the base value of
`BuiltInWorkgroupId`, and thus of `BuiltInGlobalInvocationId`. Metal
provides no direct support for this... but it does provide a builtin,
`[[grid_origin]]`, normally used to pass the base values for the stage
input region, which we will now abuse to pass the dispatch base and
avoid burning a buffer binding.

`[[grid_origin]]`, as part of Metal's support for compute stage input,
requires MSL 1.2. For 1.0 and 1.1, we're forced to provide a buffer.

(Curiously, this builtin was undocumented until the MSL 2.2 release. Go
figure.)
