This change resolves some type-related issues that were leading to
loss-of-precision warnings when compiling for i386 in OSS-Fuzz.

Vasyl Teliman 979a0b4446 Fix CLI parameters in fuzzers
This CL changes the prefix of CLI parameters in AST and SPIRV-Tools
fuzzers from `--` to `-` to make these fuzzers compatible with ClusterFuzz.
Additionally, a `tint_` prefix was added to all CLI arguments to prevent their
name collisions with LibFuzzer arguments.

Vasyl Teliman 0b3611b8c8 Add spirv-tools fuzzer
This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.

The list of all supported CLI arguments and their description is in the cli.h file.
