Instead of a std::string. This avoids unnecessary string allocations, and follows the pattern of all other AST nodes.

Currently the `is_reserved` method in the WGSL parser uses the
`operator==` on the token to check the reserved words. This ends up
re-doing a bunch of work as it checks the token type, then gets the
`string_view` or `string` from the variant, then compares.
This CL adds a precondition that the token is an identifier (which is
true in the only case we call this method) and then extracts the string
from the token once and uses that for all the comparisons.
