commands.bot_has_permissions doesn't work for slash or bridge commands in dms

[Revnoplex]

Summary

bot_has_permissions works fine for prefix commands in dms but throws an error when using slash commands or bridge commands

Reproduction Steps

create a slash command or bridge command
note: this was in a cog (not sure if it occurs otherwise)
use the bot_has_permissions check
try running the command in dms

Minimal Reproducible Code

@commands.slash_command(name="test", description="Hello World")
@commands.bot_has_permissions(send_messages=True)
async def test(self, ctx):
    await ctx.respond("Hello World")

Expected Results

correctly invoke the command and not throw an error like a prefix command usually does.

Actual Results

throws an error from /lib-dir/ext/commands/core.py on line 2082

permissions = ctx.channel.permissions_for(me)  # type: ignore

AttributeError: 'PartialMessageable' object has no attribute 'permissions_for'.

This appears to stem to another issue where dm channels will always appear as partial messagables

[Revnoplex]

the issue didn't fix its now occuring on line 2119!

Why not use discord.default_permissions instead

[Revnoplex]

does it work with bridge commands?

[Revnoplex]

is there a bot_has_permissions equivalent?
