Update the FileIO Aliases (#4186)

* Update the FileIOAlias naming to make the cache, project root and engine
root paths more clear

The alias of `@root@`, `@assets@`, and `@projectplatformcache@` has been
collapsed to `@projectproductassets@`

The alias of `@devroot@` and `@engroot@` has been collapsed to
`@engroot@`

The alias of `@devassets@` and `@projectroot@` has been collapsed to
`@projectroot@`

* Updated use of devassets and devroot properties in python

Those properties now use projectroot and engroot

The ResolvePath function now just appends the @projectproductassets@
alias with the input path

* Added a deprecated alias map to the FileIO System

When a deprecated alias is accessed, the FileIO System logs an AZ_Error and indicates the alias that should be used

Removed the Path constructors which accepts a PathIterable instance

The PathIterable isn't safe to return to a user of the Path class as it might be referencing temporary paths supplied via PathView arguments

It needs to return the *this path if the pathResult is empty

* Moved the LocalFileIO ConvertToAbsolutePath implementations to AZ::Utils

Fixed the ConvertToAbsolutePath implementation for Unix platforms to use a buffer that is size PATH_MAX(4096 on all our supported Unix platforms).
Because the buffer before was AZ::IO::MaxPathLength which as a size of 1024, this was resulting in the Unix `realpath` function smashing the stack when it converts a path to an absolute path that is longer than 1024 characters

* Updated the LocalFileIO::ResolvePath function to use HasRootPath to determine if a path starts with a root path such as "D:", "D:/" or "/"

IsAbsolute was not the corect check as the path of "D:" is a relative
path.
To be absolute according to the Windows the path must have a root
directory. i.e "D:/" or "D:\"

Those tests no longer use the logic `azlmbr.paths.projectroot / "Cache" / "pc"` to retrieve a path to the cache root but instead the `azlmbr.paths.projectproductassets` constant
