fix(parser): store lone surrogates in TemplateElementValue as escape sequence

[overlookmotel]

Encode lone surrogates in cooked property of TemplateElementValue using same encoding scheme as for StringLiterals.

In fact, they were already being encoded like this after #10041, but add a lone_surrogates flag to TemplateLiteral to decode them correctly in ESTree AST.

oxc_codegen ignores cooked and just prints raw, so needs no alteration.
