Fix handling of OpExtInstImport
The assembler tracks mapping of extended instruction import Id
to extended instruction type.
Adds a few new ways to fail.

Assembler supports hex float constants.
The bit pattern for a hex float is preserved through
assembly and disassembly.
You can use a hex float to express Inf and any kind of NaN
in a portable way.

Print OpConstant values according to type.
Zero and normal floating point values are printed with enough
enough digits to reproduce all the bits exactly.
Other float values (subnormal, infinity, and NaN) are printed
as hex floats.
Fix a binary parse bug: Count partially filled words in a
typed literal number operand.
TODO: Assembler support for hex numbers, and therefore reading
infinities and NaNs.

spv_operand_type_t cleanup.
- Concrete operand types are never optional.
Split them to make this so, e.g. add SPV_OPERAND_TYPE_IMAGE
since there was SPV_OPERAND_TYPE_OPTIONAL_IMAGE.
Similarly for SPV_OPERAND_TYPE_MEMORY_ACCESS.
This entails duplicating two operand table entries.
- The above, plus some rearranging of enums, allows us to define
first and last optional operand types, and first and last
variable operand types.
This lets us simplify the code for spvOperandIsOptional, and
spvOperandIsVariable.
- Replace SPV_OPERAND_TYPE_MULTIWORD_LITERAL_NUMBER with the
more accurately named SPV_OPERAND_TYPE_TYPED_LITERAL_NUMBER.
Its special characteristic is that the type of the literal
number is determined by some previous operand in the instruction.
This is used for literals in OpSwitch, OpConstant, and OpSpecConstant.
This lets us refactor operand parsing cases in the assembler.
- Remove the special required-thing-in-optional-tuple in favour of
the corresponding concrete operand type:
SPV_OPERAND_TYPE_ID_IN_OPTIONAL_TUPLE
--> SPV_OPERAND_TYPE_ID
SPV_OPERAND_TYPE_INTEGER_LITERAL_IN_OPTIONAL_TUPLE
--> SPV_OPERAND_TYPE_INTEGER_LITERAL
- Constrain spvOpeandTypeStr to only have to work for non-variable
operand types. Add a test for this.

Refactor the binary parser.
The binary parser has a C API, described in binary.h.
Eventually we will make it public in libspirv.h.
The API is event-driven in the sense that a callback is called
when a valid header is parsed, and for each parsed instruction.
Classify some operand types as "concrete". The binary parser uses
only concrete operand types to describe parsed instructions.
The old disassembler APIs are moved into disassemble.cpp
