Added coverage for abrupt completion returning cases in ToNumber called by math

[G-Lee1031]

Hello.
This PR covers 26 cases of Math method where ToNumber is returned with an abrupt completion.

I have added a total of 77 files. Aside from two specific cases (explained below), the remaining 75 files follow a consistent pattern to test the error-handling path of the ToNumber operation for each Math method.

1. Common Test Patterns (75 files)

• Case 01 (*-tonumber01.js): when an argument is a BigInt, ToNumber throws a TypeError.
• Case 02 (*-tonumber02.js): when an argument is a Symbol, ToNumber throws a TypeError.
• Case 03 (*-tonumber03.js): when ToPrimitive is called and returns an abrupt completion.

Specifically in this PR, I made ToPrimitive throw a TypeError by setting argument as {toString: undefined, valueOf: undefined} so that ToPrimitive throws in its 1.d step, where
OrdinaryToPrimitive(O, hint) is called and throws in step 4.

2. Specific Cases (2 files)

These two were named differently because a similar example where ToNumber throws because of valueOf existed.

• Math.hypot_ToNumberErr02.js: when an argument is a BigInt, ToNumber throws a TypeError.
• Math.hypot_ToNumberErr03.js: when an argument is a Symbol, ToNumber throws a TypeError.

Covered Methods

The tests cover the following 25 Math methods (3 files each):
abs, acos, acosh, atan, atan2, cbrt, ceil, cos, cosh, exp, f16round, fround, imul, log, log10, log2, max, min, pow, round, sin, sinh, sqrt, tan, tanh.

Can you name the files descriptively, please, instead of numbering them?

(also, please be sure to not use an LLM for open source contributions)

Thank you for the detailed feedback!

Regarding the file names, I named them *-tonumber01... to keep them consistent with my previous PRs, but I understand your point. Also, just to clarify—I wrote all the code manually without using any LLMs. :)

I realize that 77 files can be overwhelming to review, and I apologize for the heavy load. I grouped them together because they all share the exact same logic and format.

Would it be better if I renamed them to something more descriptive like abs-tonumber-bigint? Please let me know if this works for you, or if you have a preferred naming convention!

Yes, names like abs-tonumber-bigint.js would be strongly preferred.
