feat(treesitter): allow disabling captures and patterns on TSQuery (#32790)

Problem: Cannot disable individual captures and patterns in treesitter queries.

Solution: 
* Expose the corresponding tree-sitter API functions for `TSQuery` object. 
* Add documentation for `TSQuery`.
* Return the pattern ID from `get_captures_at_pos()` (and hence `:Inspect!`).

+--- Reference to an object held by the treesitter library that is used as a
+--- component of the |vim.treesitter.Query| for language feature support.
+--- See |treesitter-query| for more about queries or |vim.treesitter.query.parse()|

+--- Disable a specific capture in this query; once disabled the capture cannot be re-enabled.
+--- {capture_name} should not include a leading "@".
+---
+--- Example: To disable the `@variable.parameter` capture from the vimdoc highlights query:
+--- ```lua
+--- local query = vim.treesitter.query.get('vimdoc', 'highlights')
+--- query.query:disable_capture("variable.parameter")
+--- vim.treesitter.get_parser():parse()
+--- ```
+---@param capture_name string
+function TSQuery:disable_capture(capture_name) end
+
+--- Disable a specific pattern in this query; once disabled the pattern cannot be re-enabled.
+--- The {pattern_index} for a particular match can be obtained with |:Inspect!|, or by reading
+--- the source of the query (i.e. from |vim.treesitter.query.get_files()|).
+---
+--- Example: To disable `|` links in vimdoc but keep other `@markup.link`s highlighted:
+--- ```lua
+--- local link_pattern = 9 -- from :Inspect!
+--- local query = vim.treesitter.query.get('vimdoc', 'highlights')
+--- query.query:disable_pattern(link_pattern)
+--- local tree = vim.treesitter.get_parser():parse()[1]
+--- ```
+---@param pattern_index integer
+function TSQuery:disable_pattern(pattern_index) end
