[compiler:codegen] Wrap non-ascii characters in JsxExpressionContainer

This PR extends the previous logic added in #29141 to also account for
other kinds of non-ascii characters such as `\n`. Because these control
characters are individual special characters (and not 2 characters `\`
and `n`) we match based on unicode which was already being checked for
non-Latin characters.

This allows control characters to continue to be compiled equivalently
to its original source if it was provided in a JsxExpressionContainer.
However note that this PR does not convert JSX attributes that are
StringLiterals to JsxExpressionContainer, to preserve the original
source code as it was written.

Alternatively we could always emit a JsxExpressionContainer if it was
used in the source and not try to down level it to some other node
kind. But since we already do this I opted to keep this behavior.

Partially addresses #29648.
