chore(fuzz): Fuzz the SSA parser

[aakoshh]

Description

Problem*

Related to #8620

Some parts of the SSA Instruction may not be displayed by the printer, which means the information would not survive an SSA print+parse roundtrip.

Summary*

Adds a new test under the ast_fuzzer which generates an arbitrary Program, chooses an arbitrary SSA pass, compiles the program up to that point, prints the SSA into a string, parses the SSA, then compares that all values in the DFG are the same.

Run it like so:

cargo test -p noir_ast_fuzzer --test parser

or to replicate a failure:

NOIR_ARBTEST_SEED=0x9ecc135e00100000 cargo test -p noir_ast_fuzzer --test parser

Additional Context

It fails currently with various seeds. One problem based on the 3rd example seems to be that the parser must be going in the order of appearance of blocks, which has been changed to alphabetical order, rather than following the CFG topological ordering, so it looks for IDs before they are defined.

v36 = make_array b"\u{c}"
                     ^^^^
                     '\u' is not a valid escape sequence. Use '\' for a literal backslash character.

                                         ^^^^^

                             ^^^^
                             Unknown variable 'v262'
