It is a dictionary attribute containing the SPIR-V version, supported extension list, and allowed capability list. A SPIRVConversionTarget subclass is created to take in the target environment and sets proper dynmaically legal ops by querying the op availability interface of SPIR-V ops to make sure they are available in the specified target environment. All existing conversions targeting SPIR-V is changed to use this SPIRVConversionTarget. It probes whether the input IR has a `spv.target_env` attribute, otherwise, it uses the default target environment: SPIR-V 1.0 with Shader capability and no extra extensions.

This enables us to add verification hooks in the SPIR-V dialect to verify them.

This commit extends to allow specifying availability spec on enum cases. Extra utility functions are generated for the corresponding enum classes to return the availability requirement. The availability interface implemention for a SPIR-V op now goes over all enum attributes to collect the availability requirements.

These mechanisms are considered as different availability classes. This commit introduces basic definitions for modelling SPIR-V availability classes. Specifically, an `Availability` class is added to SPIRVBase.td, along with two subclasses: MinVersion and MaxVersion for versioning. SPV_Op is extended to take a list of `Availability`. Each `Availability` instance carries information for generating op interfaces for the corresponding availability class and also the concrete availability requirements. With the availability spec on ops, we can now auto-generate the op interfaces of all SPIR-V availability classes and also synthesize the op's implementations of these interfaces. The interface generation is done via new TableGen backends -gen-avail-interface-{decls|defs}. The op's implementation is done via -gen-spirv-avail-impls.
