Update grammar table generation:
- Get extensions from instructions, not just operand-kinds
- Don't explicitly list extensions that come from the SPIR-V core
grammar or from a KHR extended instruction set grammar.
This makes it easier to support new extensions since the recommended
extension strategy is to add instructions to the core grammar file.
Also, test the validator has trivial support for passing through
the extensions SPV_NV_shader_subgroup_partitioned and
SPV_EXT_descriptor_indexing.
Migrating to unified grammar means we sometimes have two fields
for a certain feature: version and extensions. It means the feature
in question can be used either in SPIR-V of advanced-enough
versions or in any SPIR-V with with the specified extensions.
Validator now respects the above rules.
This needs custom code since the rules from the extension
are not encoded in the grammar.
Changes are:
- The new group instructions don't require Group capability
when the extension is declared.
- The Reduce, InclusiveScan, ExclusiveScan normally require the Kernel
capability, but don't when the extension is declared.

Re-formatted the source tree with the command:
$ /usr/bin/clang-format -style=file -i \
$(find include source tools test utils -name '*.cpp' -or -name '*.h')
This required a fix to source/val/decoration.h. It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.
Use the list from the SPIR-V registry page. Also, capture it as
a string so it's much easier to update via copy-paste.
The validator will accept modules that declare these known
extensions. However, we might not know about new tokens or
instructions declared in them. For that we need grammar updates
applied to SPIRV-Headers.
Supported in assembler, disassembler, and binary parser.
The validator does not check SPV_AMD_gcn_shader validation rules
beyond parsing the extension.
Adds generic support for generating instruction tables for vendor
extensions.
Adds generic support for extensions the validator should recognize
(but not check) but which aren't derived from the SPIR-V core
grammar file.

Autogenerating the following code:
- extension enum
- extension-to-string
- string-to-extension
- capability-to-string
Capability mapping table will not compile if incomplete.
TODO: Use "spirv-latest-version.h" instead of 1.1.
Added function to generate capability tables for tests.
Known extensions are saved in validation state. Unknown extension
produce a dignostic message, but do not fail the validation.
Moved extension definitions to their own file.
