Allow arbitrary path lengths in compiler

[riftEmber]

Removes usages of FILENAME_MAX and other hardcoded buffers for path strings, enabling the use of arbitrarily long file paths.

This PR has the same purpose as #17517, but isn't based off of it as the prior PR was too far behind main.

Resolves #26261 and contributes to #8757.

definitely outside the scope of this PR, but it would be nice to change 'S' to use std::string too. Maybe open an issue for refactoring the arg parsing code to use more modern C++?

[riftEmber]

Is there something you would want to see change about how it functions, besides the internals? I feel "if it ain't broke" about refactoring it, personally.

[jabraham17]

Nothing specific in terms of the API, I mostly am just tired of dealing with very old C-style C++ code, which is true for much of the compiler

I feel "if it ain't broke" about refactoring it, personally.

I kinda tend to agree, but I think there is an aspect of "leave things better than you found it" too. Definitely not advocating you do anything in this regard for this PR.
