  [clang][lex] Fix lexing malformed pragma within include directive (#138165)

this patch fixes a crash triggered by lexing past eof when emitting a
diagnostic for a malformed `_Pragma` directive within an `include`
directive.
Fixed by by preventing the lexer from eating a `tok::eod`.

Fixes #138094
