Support coloring a subset of the matched brackets

[hediet]

This issue changes the behavior when both brackets and colorizedBracketPairs are configured, for example through this configuration:

"[plaintext]": {
    "editor.language.brackets": [
      ["{", "}"],
      ["(", ")"],
      ["[", "]"]
    ],
    "editor.language.colorizedBracketPairs": [
      ["{", "}"],
      ["<", ">"]
    ]
  },

In this case, the four bracket pairs {}, (), [] and <> should be matched.
However, only the pairs {} and <> should get highlighted.

In particular, this restores the bracket matching behavior for plain text files before colorization was introduced.

Verification Steps

Configure editor.language.brackets and editor.language.colorizedBracketPairs and verify that the former just matches brackets and the latter colorizes them. Verify they can be configured independently.

I wonder if there is any use to disable 'match' highlighting on brackets that are only listed in editor.language.colorizedBracketPairs, but not editor.language.brackets
for example, the angle brackets in the gif would be coloured but wont have the squares boxes around them

this would mean that if editor.bracketPairColorization.enabled is disabled, <> wouldn't be coloured or have match highlighting
and thus would be visually treated as normal text, but still retain internal nesting levels

What would be your use-case?

I don't have any atm
was just an idea that possibly someone else might want/need

[RedCMD]

Not sure if this is a bug or feature (I would incline towards feature)
if a bracket pair is listed under "brackets" but not "colorizedBracketPairs"
it can still be marked as invalid if it is not matching in a document

[ is marked as invalid, even tho it is not under "colorizedBracketPairs"

This was a compromise, as for unclosed/unopened brackets we don't really know if it is colorized or not, as that depends on the missing opening/closing bracket (only complete pairs are colorized and different pairs can share brackets).
However, I'm just considering a change that brackets that are not colorized in any pair don't get red when they are unopened/unclosed. This fixes https://stackoverflow.com/questions/75610880/why-are-some-left-and-right-angle-brackets-colored-red-in-vscode and others for now.
