Fix cmdutil.PrintTable to handle ansi escapes and non-byte glyphs (#8344) 
Fixes two bugs in how padding was calculated in PrintTable.

Firstly we remove all ANSI escape codes from the string before measuring
how wide it is. Secondly we measure glyph count (using rivo/uniseg) not
byte or rune count of the string.

Together these fix the padding/alignment issues I saw when using
PrintTable with plan output. They also slightly change the layout of
"pulumi stack", for example the below is printed with current master and
has 6 characters of space for padding between SecurityGroup and
web-secgrp:

```
Current stack resources (4):
    TYPE                                        NAME
    pulumi:pulumi:Stack                         aws-cs-webserver-test
    ├─ aws:ec2/securityGroup:SecurityGroup      web-secgrp
    ├─ aws:ec2/instance:Instance                web-server-www
    └─ pulumi:providers:aws                     default_4_25_0
```

While printed with this commit you only get 2 characters of space for
padding (which is correct, the column gap is set to "  "):
```
Current stack resources (4):
    TYPE                                    NAME
    pulumi:pulumi:Stack                     aws-cs-webserver-test
    ├─ aws:ec2/securityGroup:SecurityGroup  web-secgrp
    ├─ aws:ec2/instance:Instance            web-server-www
    └─ pulumi:providers:aws                 default_4_25_0
```

Pulumi Golang SDK

This directory contains support for writing Pulumi programs in the Go language. There are two aspects to this:

  • pulumi/ contains the client language bindings Pulumi program's code directly against;
  • pulumi-language-go/ contains the language host plugin that the Pulumi engine uses to orchestrate updates.

To author a Pulumi program in Go, simply say so in your Pulumi.yaml

name: <my-project>
runtime: go

and ensure you have pulumi-language-go on your path (it is distributed in the Pulumi download automatically).

By default, the language plugin will use your project's name, <my-project>, as the executable that it loads. This too must be on your path for the language provider to load it when you run pulumi preview or pulumi up.
