Changes various fuzz targets so that the target back-end language (HLSL,
MSL, SPIR-V or WGSL) is no longer passed as a command line argument, but
instead baked into the fuzzer's binary. This avoids a problem whereby a
ClusterFuzz bug reproducer does not use the required back-end command
line argument.

Added function in node_id_map to check a given id is valid and fresh.
Currently, the structure of FindMutators declares node_id_map as const, which causes issues when we want to call `GetFreshId` from the argument that is passed by reference. A simple work around is to pass a non-const node_id_map as argument directly. That way `GetFreshId` function in node_id_map can continue to be non-const and conveniently update next fresh id whenever a fresh id has been taken.

Fix the infinite loop caused by 6e459fecb7.
That commit changed the behaviour of a sem::Statement::Block method for
sem::BlockStatement instances. Now, the method returns the block itself
instead of the outer block which causes an infinite loop when iterating
over a chain of blocks.

Fuzzers like to generate silly long source, and formatting large spans of these can take considerable time.
Only format the diagnostic if it is going to be displayed.
Significantly speeds up some fuzzing tests, fixing some timeouts.
Also add a minor optimization to the formatter repeat() implementation.

Currently, AST fuzzer requires that all fuzzed binaries are serialized protobuf messages.
In principle, we don't need this when we don't record mutations (which is the case right
now). Hence, this CL removes that requirement.

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.
