af7125dfb0 Validation of type decls for SPV_KHR_16bit_storage

the presence of capabilities from SPV_KHR_16bit_storage

c6099ad242 Add a Feature struct to validation state.
For now, it is used only for checks of 16bit int and float types.

8c414eb579 Adding validation code for OpTypeStruct.
According to the Data Rules section of 2.16.1. Universal Validation
Rules of the SPIR-V Spec:

Forward reference operands in an OpTypeStruct
* must be later declared with OpTypePointer
* the type pointed to must be an OpTypeStruct
* had an earlier OpTypeForwardPointer forward reference to the same <id>

d0620061c7 Adding validation code for more data rules.
These rules are under "Data Rules" in 2.16.1 (Universal Validation
Rules) part of the SPIR-V 1.1 Specification document:

* Scalar floating-point types can be parameterized only as 32 bit, plus
any additional sizes enabled by capabilities.

* Scalar integer types can be parameterized only as 32 bit, plus any
additional sizes enabled by capabilities.

* Vector types can only be parameterized with numerical types or the
OpTypeBool type.

* Matrix types can only be parameterized with floating-point types.

* Matrix types can only be parameterized as having only 2, 3, or 4
columns.

* Specialization constants (see Specialization) are limited to integers,
Booleans, floating-point numbers, and vectors of these.

6c899a52f9 Adding validation for vector data rule.
Number of components in a vector can be 2 or 3 or 4. If Vector16
capability is used, 8 and 16 components are also allowed.
Also added unit tests for vector data rule.
