Chandler Carruth fccb349af4 Improve the TextMate grammar scopes and precision (again) (#7914) 
This is a re-do of #7888

Outside a call, the grammar scoped a name as a type or a variable by its
capitalization. A theme could not distinguish a type from a value with
the same spelling, or a parameter, a member, or an implemented interface
from any other name. Pointer member access `->` was scoped as a result
arrow, which scoped `Lookup` in `regions->Lookup(x)` as a type.

`entity.name.type` now applies only in a type position (after `:`, `->`,
`as`, `adapt`, or `require`, or in an `impl`) and to the name a nominal
declaration declares. A qualifier, in a declared name like `fn N.Base(T:
type).F()` or in a type, is `entity.name.scope-resolution` nested in
`entity.name.type`. As in the parser, a name is a qualifier when its
parameter lists are followed by `.`. Parameters, `let` bindings, choice
alternatives, members, implemented interfaces, primitive types,
`import`, and the strings naming a builtin or a library have their own
scopes, and brackets use the C++ grammar's scopes. A `->` written
directly after its operand is member access; no result arrow in the
repository is written that way.

The sample palette renders each scope that depends on context
differently, and `tmlanguage.py` now supports nested captures.

In 17 of the 19 themes measured, the VS Code built-ins plus One Dark
Pro, Night Owl, Tokyo Night, and Nord, 13% to 27% of the characters in
hand-written Carbon change color or style. A theme loses a color where
`.` is now punctuation, where word operators like `as` are no longer
control-flow keywords, or where a name outside a type position is no
longer a type.
