Allow VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT

This CL allows the use of VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT.
When set, the implementation may skip any unnecessary processing needed
to support simultaneous modification from multiple threads where allowed.

This CL includes no optimization and simply allows the use of the bit as a noop.

Tested locally by applying the following change:
https://gerrit.khronos.org/c/vk-gl-cts/+/10186/2/external/vulkancts/modules/vulkan/pipeline/vktPipelineCacheTests.cpp

Of the new tests added, only a single test is actually supported at this point, but it now passes:
dEQP-VK.pipeline.monolithic.cache.graphics_tests.vertex_stage_fragment_stage_externally_synchronized

Tests: dEQP-VK.pipeline.*.cache.graphics_tests.vertex_stage_*_externally_synchronized
