[BUG] Console.size returns the wrong width if legacy_windows is True

[x] I've checked docs and closed issues for possible solutions.
[x] I can't find my issue in the FAQ.

Describe the bug

There is no need to subtract self.legacy_windows from self._width in the size getter (link) because the self._width field already contains a value that takes legacy_windows into account (link).

For example, you can't directly get the size value from one console and assign it to another. The width of the second console will be 1 character smaller.

from rich import get_console
from rich.console import Console

console  = get_console()
econsole = Console(stderr=True)

print("Before:\nconsole.size  =", console.size, "\neconsole.size =", econsole.size)

econsole.size = console.size

print("After:\nconsole.size  =", console.size, "\neconsole.size =", econsole.size)

Output:

Before:
console.size  = ConsoleDimensions(width=182, height=26)
econsole.size = ConsoleDimensions(width=182, height=26)
After:
console.size  = ConsoleDimensions(width=182, height=26)
econsole.size = ConsoleDimensions(width=181, height=26)
