fix(babel-plugin-lingui-macro): unwrap non-null assertion (x!) and satisfies in placeholders (#2622)

`tokenizeExpression` only unwrapped `TSAsExpression`, so a placeholder like
`t`${x!}`` was treated as a complex expression and assigned an indexed
placeholder (`{0}`), whereas `@lingui/swc-plugin` unwraps it to a named
placeholder (`{x}`). This produced different message IDs for identical source,
breaking catalog lookups in projects that extract with the JS macro but run
with the SWC plugin.

Unwrap `TSNonNullExpression` and `TSSatisfiesExpression` alongside
`TSAsExpression` so all TS-only wrappers name the inner expression, matching
the SWC plugin and the existing `as` behavior.
