Add Triton Backend

[PaliC]

This PR adds a triton backend to kernel bench. To invoke it simply add backend="triton" to the following 4 scripts (use them as normal otherwise)

scripts/generate_and_eval_single_sample_modal.py
scripts/generate_and_eval_single_sample.py
scripts/generate_samples.py
scripts/eval_from_generations.py

This PR also adds a {error_type}_name into the eval json. The reason for this is that it makes classifying errors (especially for triton) much easier. For example, from the error log it isn't obvious what an error is (ie. you might get at 37:15:\n h_start = pooled_row * stride - padding\n w_start = pooled_col * stride - padding\n\n # Initialize the max value\n max_val = tl.full((1,), float('-inf'), tl.float32)\n\n # Itera...). But if the error name is triton.compiler.errors.UnsupportedLanguageConstruct it's a lot more obvious.

Testing: I've tested the 4 scripts in both the triton and cuda variants and they seem to work normally. (outside of scripts/generate_and_eval_single_sample_modal.py which should be equivalent to scripts/generate_and_eval_single_sample.py)

Todo:

• This PR is a little bit crude as it just adds the logic (and linting (sorry meta's IDE does this automatically). There are other things like updating the readme, and a bit of logical refactoring (use kernel instead of cuda for example). But I will leave that to a followup PR as this one is already 1000 lines.
• Add fewshot for triton
• Add CoT for triton

Below is the github copilot generated summary which is honestly pretty useful for navigating large PRs.

==========================================================================================
This pull request includes several changes to improve code readability and add new functionality to the scripts/eval_from_generations.py and scripts/generate_and_eval_single_sample.py files. The most notable changes include reformatting code for better readability, adding a new backend configuration option, and enhancing error logging.

Code readability improvements:

• scripts/eval_from_generations.py: Reorganized import statements and reformatted multiple lines of code to follow PEP 8 guidelines.
• scripts/generate_and_eval_single_sample.py: Reorganized import statements and reformatted multiple lines of code to follow PEP 8 guidelines.

New functionality:

• scripts/eval_from_generations.py: Added a new configuration option backend to specify the backend for kernel implementation (cuda or triton).

Error logging enhancements:

• scripts/eval_from_generations.py: Enhanced error logging by adding more detailed error messages and including error names in the metadata. [1] [2]

Miscellaneous:

• scripts/eval_from_generations.py: Added indentation to JSON output in add_to_eval_results_file for better readability.
• scripts/generate_and_eval_single_sample.py: Added the backend configuration option to the EvalConfig class.
