1. Closed previous "Upgrade to TS 5.6.2” PR
2. git fetch upstream
3. git checkout upstream/release-5.7 and ensured it was on the commit of the release.
4. git checkout -b branch_v5.7.3
5. git push denoland
6. git checkout -b branch_v5.7.3_patch
7. Cherry picked changes in from denoland/branch_5.6.5_patch into denoland/branch_v5.7.3_patch and squashed the commits
8. npm install && npx hereby services dts-services (to build)
   • If you get a diagnostic about globals or globalThisSymbol not existing, it's because they're called denoGlobals/nodeGlobals and denoGlobalThisSymbol/nodeGlobalThisSymbol in this fork
   • If there are new usages of globals or globalThisSymbol in checker.ts, update that code to be properly handled using either denoGlobals/nodeGlobals or denoGlobalThisSymbol/nodeGlobalThisSymbol (note: globalThisType refers to the global this type and not the global globalThis type)
9. cp built/local/typescript.js ../deno/cli/tsc/00_typescript.js
10. Copied the .d.ts files from built/local to ../deno/cli/tsc/dts then deleted files that didn't seem necessary (ex. typescript.internal.d.ts).
11. Reviewed the dts files and made any modifications (reverts) necessary
12. Search for "5.6.2" in the Deno codebase and replace with the new version
13. Check if ScriptElementKind in the ts codebase has changed and if so, align with ScriptElementKind in cli/lsp/tsc.rs
14. Ran cargo test check and cargo test lsp
15. Opened this PR with base branch_v5.7.3 from denoland repo
