According to Table 20.45 and Chapter 17 in the ES 3.1 spec, MAX_COMPUTE_WORK_GROUP_COUNT
is get as a GLint by using GetIntegeri_v. However, it is an unsigned integer
in the Vulkan. It needs to set limitation on maxComputeWorkGroupCount[] during
translating.

1. Change the data type to GLint stored in Caps.
2. Ensure that the limitation is set during initialization.
3. Add workaround for angleproject:4120

Bug: angleproject:4066
