* Extend RuntimeHelpers.IsBitwiseEquatable to more types

Today, RuntimeHelpers.IsBitwiseEquatable is hardcoded to a fixed list of types.  This means that almost all of the vectorization we've done with arrays and spans is limited to just those types; developers can themselves use MemoryMarshal.Cast to convert spans of other types to spans of supported one, but it doesn't naturally happen.

This extends IsBitwiseEquatable a bit more. We already have a CanCompareBitsOrUseFastGetHashCode helper used by ValueType.Equals to determine whether structs that don't override Equals can be compared with the equivalent of memcmp.  This extends that same helper to be used by IsBitwiseEquatable.  However, IsBitwiseEquatable also needs to rule out types that implement `IEquatable<T>` (the existing helper doesn't because it's about the implementation of the object.Equals override where the interface doesn't come into play).

The upside of this is APIs like Array.IndexOf will now automatically vectorize with more types.  The main downside is that types which provide their own equality implementation still don't benefit, which in turn means adding an `IEquality<T>` implementation could in the future be a deoptimization (we should consider some kind of attribute or marker interface a type can use to say "I promise my equality implementation is the same as a bitwise comparison").  We also currently constrain most of our MemoryExtensions methods to types that implement `IEquatable<T>`, so there are only a handful of public methods today that benefit from this.

* Fix incorrect SpecialFolder entries for Unix

Fix #63214

* Don't make Unix tests assume Personal is Home

* Use the same value for Mac's (Local)ApplicationData

* Use NSPaths for OSX Special Folder

The Apple documentation recommends to use these instead of hardcoding the paths, so the paths that had NSPath equivalents have been replaced.

* Change System.Native CMakeLists to include OSX for SearchPath

`a17e73466ca639388a3d89f4d6be0ab9703802fc` made OSX call the native NSearchPath functions, however a stub was initially called. This fixes it to call the native functions.

* perf-pipeline: Set default value for ExtraSetupArguments

Fixes `line 1: ExtraSetupArguments: command not found` when running
performance/scripts/ci_setup.py .

* perf pipeline: Disable unncessary scheduled builds

`dotnet-runtime-perf` runs:
1. batched builds
2. scheduled builds at 2:30am every night

For the 'scheduled' case, only wasm/jsc perf jobs are run.
And the rest are build jobs - wasm, mono, coreclr, and libraries.

The wasm/jsc runs are known to be broken right now, thus they can be
disabled. And since there are no other perf jobs, none of the remaining
builds are needed, thus the whole scheduled run can be disabled.

The function has an early return if tmp is ever null, so there is no need to have this check here.

AddRange is currently implemented as delegating to InsertRange, and InsertRange in turn has a more complicated inner loop as part of adding each item from a source enumerable into the list.  By just copying InsertRange's source into AddRange, deleting all the irrelevant stuff, and changing the Insert call to Add, throughput improves measurably.

Previously, if there was any diff in a collection, that collection would
be shown in all tables (i.e. Overall, FullOpts, MinOpts). The main
reason was that we only had "has diffs" information on a per-collection
basis, not for each of the categories. This changes SPMI to communicate
back for each category how many contexts had diffs in them, and uses
this to hide tables/rows without any diffs, and to show this information
under details.

* Add new convert tests

With expression funcs that return int32 instead of short/byte to prevent implicit conversions.

* Add back missing conv opcodes when compiling via System.Linq.Expressions

The conversion opcodes are still necessary when the sign of the value might change, in which case the conversion opcode will do a sign/zero extend to the full i32 storage used by the IL execution stack.

For example, before this change, conversions from ushort to short were ignored. Consider expressions converting the value `ushort.MaxValue` to short (testcase ConvertUShortToShortTest). `ushort.MaxValue` will be pushed to execution stack as a i32 ldc of value 0xffff. The conv.i2 opcode would change the value on the stack to 0xffffffff so it shouldn't be omitted.
