std.math.big.int: fix shiftRight sign handling
...
Closes #21311
The sign of the result `r` needs to be initialized before the correction
`r.addScalar(r.toConst(), -1)`, or the intended end result could be off
by 2 (depending on the original sign of `r`).

std: update std.builtin.Type fields to follow naming conventions
...
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938 .

std.math: rework modf
...
- Changed `modf_result` to `Modf` to better fit naming conventions
- Reworked `modf` to be far simpler and support all floating point types (as well as vectors) (I have done benchmarks and can confirm that the performance is roughly equivalent to the old implementation)
- Added more descriptive tests for modf
- Deprecated `modf32_result` and `modf64_result` in favor of `Modf(f32)` and `Modf(f64)` respectively

Update frexp.zig ( #19370 )

1. Entirely rewrote frexp with generics, reducing the implementation to a single function and enabling parameters of types f80 and f16
2. Expanded upon the tests, making them more descriptive and comprehensive, and automatically generating the test bodies for each floating point type
3. Added a doctest for frexp

Remove redundant test name prefixes now that test names are fully qualified

Follow up to #19079 , which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
